The Spectral Efficiency of Successive Cancellation With Linear Multiuser Detection for Randomly Spread CDMA

We consider the problem of multiuser detection for randomly spread direct-sequence (DS) code-division multiple access (CDMA) over flat fading channels. The analysis focuses on the case of many users, and large spreading sequences such that their ratio, which is the system load, is kept fixed. Spectr...
