Conflict Resolution Protocols for Secure Multiple-Access Communication Systems,tures we introduce and analyze efficient algorithms for resolving conflicts over access to the transmission medium among communicators who are employing either public key cryptography or spread spectrum signaling. Our intention is to extend some recent results in the theory of random multiple-access

Fast Decoding Algorithms for Reed-Solomon Codes,ure communication systems commonly use a Reed-Solomon code as one method of jam protection. The importance of these codes is partly due to their superior error-correcting performance, but it is equally due to the availability of efficient decoding algorithms for them. Future requirements will exist

Pseudo-Random Sequences with a Priori Distribution,ssignment of a positive integer to each n-letter word with letters chosen from some fixed finite alphabet. A distribution is atomic if it always assigns the same integer to words that are cyclic shifts of each other. A periodic sequence of letters from the alphabet is said to realize a given distrib

Pseudo-Random Sequences with a Priori Distribution, we construct a hypergraph, the subgraphs of which correspond to a family of modified nonlinear feedback shift registers. Each shift register in a family corresponding to a spanning hypertree of the hypergraph will generate a sequence realizing the given distribution.

Fast Decoding Algorithms for Reed-Solomon Codes,for ever-larger error-control codes, but only if the decoding cost remains affordable. It is important to reduce the complexity of the decoding algorithms. These lectures explore the complexity of such algorithms.
