Abstract
In this paper, we compare the performance of two inner coding structures for concatenated codes in slow frequency-hopping spread spectrum multiple-access communication systems. It is assumed that two outer code symbols are transmitted during a hop. The first structure consists of one inner codeword per one outer code symbol, while the second structure consists of one inner codeword per two outer code symbols. We analyze the overall block error probability in asymptotic region and show that the performance of the second scheme is superior to the first one.
