摘要/Abstract

摘要：

A novel high spectrum efficiency channel encoding method called overlapped code division multiplexing (OvCDM) is presented. It is a convolutional encoding method with code rate greater than 1. Compared with traditional coded modulation (CM) technologies, OvCDM emphasizes the constrain relation between encoded codes. It is actually a blind modulation. The simulation results in the additive white Gaussian noise (AWGN) channel indicate that OvCDM can significantly improve spectrum efficiency of mobile communications systems. Meanwhile, the proposed OvCDM can ensure high decoding performance.
