Capacity of frequency-hop spread-spectrum multiple-access communication systems

0 0 0 Abstract-The information theoretic capacity of frequency-hop spread-spectrum multiple-access communication is considered. In order to account for independent encoding and decoding and private (to the sender and receiver) hopping patterns an interference channel model is adopted with K sender-receiver pairs with the ith receiver only interested in the message transmitted by the ith sender. Both synchronous and asynchronous hopping patterns are investigated. Although the channel exhibits memory in the latter case, we are able to compute the capacity region. The asymptotic normalized sum capacity is also computed. E 0 0
