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.

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

Exact, closed-form results are obtained for maximal ratio combining (MRC) diversity operating on independent and identical Ricean fading branches, while accurate approximations for equal gain combining (EGC) diversity are presented with an infinite series method.
