Abstract :
The design of a spread-spectrum modem for HF channels to combat multipath and interference effects is considered, and the performance results obtained with a prototype system are discussed. The features of the modem include automatic synchronisation, diversity operation, provision for an ARQ mode and M-ary block coding.
