Partitioned-Stream Communications for Increased Spectral Efficiency in CDMA Systems

摘要

Interleaved and partitioned spread-spectrum signaling is proposed to increase the effectively available spectral efficiency in situations where multiple uncoordinated terminals communicate with a central receiver. The concept of partitioned signaling (PS) is applied to stream-based signaling and embedded pilot signals are proposed as an effective way to achieve synchronization of the multiple signal streams.
