Quasi-synchronous code-division multiple access with high-order modulation.

Quasi-synchronous code-division multiple access with high-order modulation.

Code-division multiple access (CDMA) is a multiplexing technique where a number of users simultaneously access a transmission channel by modulating and spreading their signals with preassigned codewords. This paper studies the performance of CDMA signals with orthogonal (Walsh-Hadamard) codewords an...
