“…P ERFORMANCE of communication systems can be enhanced via various time-sharing approaches such as channel switching and parameter randomization [1], [2], [3], [4], [5], [6], [7], [8] [9]. In channel switching, a transmitter and a receiver perform time-sharing among different channels by communicating over only one channel at a given time [1], [2], [3]. In this way, improvements can be achieved in terms of the average probability of error [1], throughput [10], or channel capacity [2], [3], [4].…”
