Includes bibliographical references (pages 67-68). "A main objective in the present study is to develop adaptive techniques for communications over a jammed fading channel. An adaptive rate control policy has been introduced in section 2 to compensate for channel fading. An algorithm to implement the adaptive rate control policy is described in section 3. It is shown that the adaptive rate controlled FH/MFSK signals exhibit similar cutoff rate performance as transmissions through an unfaded channel. In an adaptive rate controlled environment, coding offers superior performance to multichannel diversity transmission. An adaptive quantizing approach, which can potentially compensate for signal fading, is also proposed"--Abstract, page i. Issued also in print format. Spread spectrum communications.
