Convolutional Coding Quasi-Synchronous CDMA System Using Real-Valued Self-Orthogonal Finite-Length Sequences

摘要：

A set of real-valued self-orthogonal sequences of a zero correlation zone is applied to a variable rate quasisynchronous CDMA system without interchannel interferences in a limited shift range. In each transmitter, the synchronizing sequence and the multi-rate data are convolved with the user sequence, and quantized to the integer signal. In a receiver, the synchronizing pulse and the data train are detected with suppressed distortions and interferences.
