This technique presents good performance assuming the absence of estimation errors for channels characterized by flat fading. In this article, the performanc

The main idea is to apply combinatorial methods to derive a formula for the probability of subsets of error sequences at the input to the decoder in terms of coefficients of a generating series.

A set of low density parity check convolutional codes is derived from this quasi-cyclic code and its generalizations. The performance of these convolutional codes is investigated when decoded using belief propagation on

In the decoding radius (up to half of the minimum distance), the new method is easily adapted for error and erasure decoding. It can also detect all errors outside the decoding radius. Compared with the BerlekampMassey algorithm, discovered in the la

Brian Norton BSc, MSc, PhD, F Inst E, C Engen neither the transmitter nor the receiver has access to channel state information. Multiple transmit antenna differential encoding/decoding schemes are explicitly constructed based on generalized orthogonal designs. The detection scheme can use equal energy constellations and encoding is simple. A

Interest in such problems has risen in recent years due to the increasing attention on quantum information processing in general. This chapter reviews the basic mathematical forma

Two large classes of Gallager codes of various lengths, rates, and minimum distances are constructed. Codes of these two classes do not contain cycles of length 4 in their Tanner graphs and they perform well with iterative dec

Since MAI is proportional to the transmit power strengths of other users, the level of transmit power by all participating users requires careful planning and control in order to attain QoS satisfaction and high system utilization.
