Abstract :
An improved partial parallel interference cancellation (PIC) detection method for V-BLAST is proposed. During every PIC stage, the substreams are detected in an ascending order of error performance from the previous stage to mitigate error propagation caused by the wrong cancellations. Simulation results are presented to show the performance improvements
