• ### Effective constraint length of 'cyclic' convolutional self orthogonal codes

Publication Year: 1981, Page(s):69 - 73
| | PDF (388 KB)

The paper shows that all 'cyclic' convolutional self orthogonal codes (CSOCs) generated by cyclic sets of even order have effective constraint lengths which meet the lower bound developed recently, and that the lower bound is a limiting bound for all CSOCs. Also, new upper bounds on the effective constraint length are developed for non-'cyclic' and 'cyclic' CSOCs. View full abstract»

• ### Properties and applications of some periodically varying digital signal processors

Publication Year: 1981, Page(s):74 - 82
| | PDF (713 KB)

A situation often encountered in a communication system, in which a digital interpolation filter is followed by a sinusoidal modulator, is considered. A mathematical model of the system is developed and some useful properties derived. These properties lead to an equivalent realisation of the interpolation filter and the subsequent commutation of the filter with the modulator. Applications to digit... View full abstract»

• ### AGC response and target glint

Publication Year: 1981, Page(s):83 - 90
| | PDF (881 KB)

Conventionally, radar trackers use fast or instantaneous¿¿ automatic gain control (AGC) loops for control of IF gain. The paper indicates that this practice may result in unnecessarily large errors when the tracking accuracy is limited by target glint¿¿ effects. The analysis considers a conical scan radar which is tracking a target consisting of two, point reflectors. Two limiting cases of AGC r... View full abstract»

• ### Performance analysis of QPSK transmission through a direct phase regenerator

Publication Year: 1981, Page(s):91 - 95
| | PDF (544 KB)

The paper considers the problem of the detection of a quaternary phase-shift-keyed signal which has been transmitted along with noise through a direct phase regenerator (DPR) corrupted by additional noise and coherently demodulated and sampled at the receiver. An expression is obtained for the symbol error probability (SEP), which includes the parameters that characterise the imperfections of a pr... View full abstract»

• ### Binary and quaternary CPSK transmissions through nonlinear channels in additive Gaussian noise and cochannel interference

Publication Year: 1981
Cited by:  Papers (1)
| | PDF (929 KB)

The paper considers the problem of evaluating the performance of binary and quaternary coherent phase-shift-keyed (CPSK) signals which have been transmitted through an arbitrary bandpass n¿¿nlinearity (BPNL) and in the presence of additive gaussian noise (AGN) and cochannel interference (CCI). Both AGN and CCI are introduced before and after the BPNL. Exact expressions are derived for the symbol e... View full abstract»

• ### Kronecker sequences for spread-spectrum communication

Publication Year: 1981, Page(s):104 - 109
Cited by:  Papers (14)
| | PDF (854 KB)

The paper considers the correlation properties of sets of sequences in which each sequence is constructed by taking the Kronecker product (or tensor product) of two short sequences. It is shown that if the short sequences are carefully chosen then the correlation properties of such sets are nearly as good as those of sequences of comparable length that have been obtained by other means. Furthermor... View full abstract»

• ### Large signal performance of feedback automatic gain control systems

Publication Year: 1981, Page(s):110 - 117
Cited by:  Papers (5)
| | PDF (805 KB)

Feedback automatic gain control (FBAGC) is used to maintain the mean level of one or more signals throughout a signal processing system at a fixed value. The paper is particularly concerned with the application of FBAGC to receiver design and discusses the problem of attempting to suppress large unwanted envelope variations of an incoming signal without distorting any wanted modulation. A simple f... View full abstract»
