A Linear Model for CDMA Signals Received with Multiple Antennas Over Multipath Fading Channels

摘要: This chapter shows how a simple linear model can be used to describe the signal received over multiple-antenna, time-dispersive, fading code-division multiple-access (CDMA) channel. The realization that each of these channel effects absorbed into general validates abstraction CDMA problem algebra which opens up mathematically elegant and powerful techniques solve common problems such as detection estimation. Based on structural principles practical systems, where all baseband processing is normally done in discrete time, we develop corresponding matrix algebraic model. leads known convenient interpretation system time-varying convolutional encoder allows for insight structure inherent interference. unifies many related models previously suggested literature. novelty this it follows systems form receiver design.
