• 論文の詳細を見る

• This paper examines the performance of a direct sequence, spread spectrum (DSSS) multiple access (MA) system used over two typical, frequency-selective, fading satellite channels. In an attempt to increase the system efficiency, an adaptive receiver described by Rapajic and Vucetic [ 1] has been implemented. This system has been combined with soft-decision convolutional coding in order to improve the system performance under the fading conditions relative to the uncoded system and to allow as many simultaneous users as possible. Various code rates have been examined and the results are given. This paper specifically focuses on DSSS-MA systems with low spreading ratios. The satellite channels used in this paper were produced by models developed as a result of experimental measurements of fading satellite channels for rural and urban environments.
