Abstract : A time division multiple access mobile communications system employing a self-adaptive feature and perfect noise codes to enable utilization of the system. The self-adaptive feature permits switching to vacant channels as interfering users move to an occupied channel. The noise codes employed are of the type termed code mates having correlation functions which upon detection provide an impulse autocorrelation function. The described arrangement enables random access to be accomplished with minimal interference between users. Large improvements in signal-to-noise power ratio and in signal-to-jamming power ratio will be seen to result. (Author)
