Analytical Performance Analysis of the Linear Multistage Partial PIC Receiver for DS-CDMA Systems
Ana Maria Barbancho, Lorenzo J. Tardón, Isabel Barbancho · IEEE Transactions on Communications · 2005
In this letter, we derive a recursive expression for the decision statistic of a linear multistage partial parallel interference cancellation (PIC) receiver for direct-sequence code-division multiple-access systems that allow us to present two closed-form expressions (exact and approximate) for the bit-error probability of this receiver. The bit-error rate is computed in terms of the number of PIC stages, set of cancellation parameters, crosscorrelation between the users' codes, amplitude of the users' signals, and noise power.
