m This paper investigates trellis structures of linear block codes for the integrated circuit (lC) implementation of Viterbi decoders capable of achieving high decoding speed while satisfying a constraint on the structural complexity of the trellis in terms of the maximum number of states at any particular depth. Only uniform sectionalizations of the code(More)
The multiplier is the building block required in the adaptive equalizer that is most costly in terms of both speed and power. Since the power consumed by a CMOS digital circuit is CV2f, reducing the power supply and employing one or a combination of parallelism and pipelining can result in a significant power savings [4]. Applications using a power supply(More)
Block codes have trellis structures and decoders amenable to high speed CMOS VLSI implementation. For a given CMOS technology, these structures enable operating speeds higher than those achievable using convolutional codes for only modest reductions in coding gain. As a result, block codes have tremendous potential for satellite trunk and other future(More)
