• ### Comparison of adaptive cell-averaging detectors for multiple-target situations

Publication Year: 1986, Page(s):217 - 223
Cited by:  Papers (11)
| |PDF (677 KB)

Conventional cell averaging (CA), greater of (GO) and smaller of (SO) constant false alarm rate (CFAR) detectors are considered when an interfering target is present in the reference noise cells. Threshold compensation techniques used previously to improve the performance of a CA detector have been modified and generalised to include GO and SO detectors. It is shown that, using these methods, good... View full abstract»

• ### Combination of cancelling intersymbol interference and decoding of error-correcting code

Publication Year: 1986, Page(s):224 - 231
Cited by:  Papers (5)
| |PDF (1036 KB)

The paper proposes and investigates a new type of nonlinear adaptive canceller of intersymbol interference (ISI) called ACDEC¿¿. The ACDEC uses an automatic equaliser including a decoder of an error-correcting code (AEDEC), to obtain more reliable preliminary decisions than those by the linear equaliser used in the linear adaptive canceller of Gersho and Lim. By using the modified structure and i... View full abstract»

• ### Further analysis of bandlimited 16-ary QAM signalling in satellite channels

Publication Year: 1986, Page(s):232 - 235
Cited by:  Papers (2)
| |PDF (428 KB)

The paper presents a method of analysing the performance of a bandlimited 16-ary quadrature amplitude modulation(QAM) signal transmitted through a bandpass nonlinearity (BPNL), exhibiting AM-AM and AM-PM conversions, and in the presence of additive Gaussian noise (AGN) both preceding and following the BPNL. To illustrate the validity and usefulness of the technique, the symbol probability of a ban... View full abstract»

• ### Low-data-rate visual communication using cartoons: a comparison of data compression techniques

Publication Year: 1986, Page(s):236 - 256
Cited by:  Papers (5)
| |PDF (5818 KB)

An analysis of two-level picture compression techniques applied to low-resolution moving images is reported. The object is to discover the most suitable technique for visual communication at low data rates using feature-extracted cartoons¿¿. Reversible facsimile compression techniques are reviewed, then results presented to demonstrate their relative performance. In general, three-dimensional tec... View full abstract»

• ### Discrimination of radar clutter by texture analysis

Publication Year: 1986, Page(s):257 - 263
Cited by:  Papers (1)
| |PDF (1483 KB)

Ground and sea clutter were discriminated by using texture analysis in image processing. As a discriminator, a nonlinear transformation of a local pattern was defined to deal with high-order statistics. The discrimination using this method indicated good performance. View full abstract»

• ### Application of the principle of dyadic symmetry to the generation of orthogonal transforms

Publication Year: 1986, Page(s):264 - 270
Cited by:  Papers (6)
| |PDF (707 KB)

Two new transforms which can be used as substitutes for the Walsh transform are generated using the theory of dyadic symmetry. The new transforms have virtually the same complexity and computational requirements as the Walsh transform, employing additions, subtractions and binary shifts only, but have an efficiency, defined in terms of their ability to decorrelate signal data, which lies between t...

• ### Go-back-N ARQ scheme with buffer at the receiver

Publication Year: 1986, Page(s):271 - 276
Cited by:  Papers (8)
| |PDF (666 KB)

In the paper a new go-back-N scheme for communication systems using error-detecting codes is described. This scheme has a buffer at the receiver side in order to introduce a memory into the go-back-N protocol. This memory and a soft demodulation of each received symbol significantly increase the performance of classical go-back-N schemes. It is also shown that, for mean and high error rate conditi...

• ### Adaptive variable update rate algorithm for tracking targets with a phased array radar

Publication Year: 1986, Page(s):277 - 280
Cited by:  Papers (1)
| |PDF (461 KB)

The analysis postulates an algorithm for adaptively varying the target-track update rate as a function of target manoeuvring. The algorithm proposes to vary the target observation time interval by an amount that tends to maintain a constant residual error. As an example, the algorithm is shown to be implemented with a two-dimensional alpha-beta filter. Simulated results are calculated for a target... View full abstract»

• ### New class of sequence sets with good auto- and crosscorrelation functions

Publication Year: 1986, Page(s):281 - 287
Cited by:  Papers (2)
| |PDF (854 KB)

A new class of nonlinearly generated sequences containing several sets all equivalent to the `small set of Kasami sequences¿¿, having optimal CCF and ACF properties, is introduced. The new class of sequences is obtained by interleaving m-sequences with the interleaving order governed by a set of sequences called the prime sequences introduced by Shaar and Davies. The construction procedure and the... View full abstract»

• ### Equivalent linear span analysis of binary sequences having an interleaved structure

Publication Year: 1986, Page(s):288 - 292
| |PDF (618 KB)

A new, general method is presented to determine the equivalent linear span (ELS) of binary sequences having an interleaved or related structure. The method is based on a polynomial representation of the interleaved sequences followed by the use of the Euclid algorithm for factorisation, to yield a minimal polynomial. The degree of this minimal polynomial can be identified as the required ELS value... View full abstract»

• ### New class of M-ary communication systems using complementary sequences

Publication Year: 1986, Page(s):293 - 300
Cited by:  Papers (1)
| |PDF (745 KB)

A new class of M-ary communication systems is introduced in which information is transmitted using long-duration waveforms that are synthesised from complementary sequences. The signal waveforms, which are detected with a correlation receiver, are such that information can be transmitted using a baud period that is much shorter than the duration of the waveforms, without any intersymbol interferen...

• ### Performance of a new class of binary communication systems

Publication Year: 1986, Page(s):301 - 312
| |PDF (1095 KB)

A new class of M-ary communication systems has been put forward as a means of reducing the effects of impulsive noise. In the paper the performance of binary systems drawn from the new general class of M-ary systems is examined both analytically and by computer simulation. A new technique based on the use of the Euler transformation of slowly convergent alternating series is developed as an aid in... View full abstract»
