    Canada is becoming increasingly dependent on satellites for communications links between remote communities and major cities. The loss of one of them is hard to evaluate, but would certainly be catastrophic. Consequently, they have become vital points requiring appropriate protection from hostile organizations. The author covers the different measures that were integrated into the Anik E telemetry... View full abstract»

  • Coding, diversity and minimum distance

    Low rate codes are sometimes used on channels that exhibit severe fading or interference. Such a low rate code may be obtained by designing a code with that rate and maximum minimum distance, or by using a higher rate code and diversity. The latter approach is usually suboptimal from a minimum distance point of view, but may have implementation advantages. The authors consider this trade-off betwe... View full abstract»

  • Highly parallel architecture for the least mean squares (LMS) algorithm

    A fast digital implementation for the least mean squares algorithm is proposed. The high concurrency of its structure allows for high processing speed with a sampling period of O(log N), where N is the number of filter taps. Chip area is minimized by the use of serial-parallel multipliers. In these multipliers, which use redundant arithmetic, the serial variables are transferred digi... View full abstract»

    The performance of a minimum redundancy array (MRA) used in conjunction with an adaptive combiner for receiving digital communications signals under co-channel interference and multipath conditions is compared with a similar system based on a uniform array. Simulation and analysis of four-element array-based systems indicate that for interference in close angular proximity to the desired signal, o... View full abstract»

  • New low-sensitivity and low-noise GIC digital filter structures

    Publication Year: 1991, Page(s):112 - 117
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1598 KB)

    New digital filter structures based on the concept of generalized-immittance convertors (GICs) are proposed. These structures are shown to possess better sensitivity and noise properties than the already known GIC structures. A comparison study is carried out using different types of sensitivity and noise measures. Further, it is shown that the limit cycles under zero-input and forced response con... View full abstract»

  • Horizontal demand prefetching: A novel approach to eliminating the jump problem

    The principle of a novel prefetching strategy, horizontal demand prefetching, is presented. This mechanism allows deep prefetching without jump-related misses by prefetching shallowly across several independent streams in a horizontal fashion. Multistream processors using this technique can achieve very high memory utilization. The mechanism supports very efficient multitasking and hardware proces... View full abstract»
