Adaptive Multiuser Decision Feedback Detector: A Novel Parallel Interference Canceller
- 52 Downloads
Adaptive decision feedback detector based on the parallel interference cancellation approach (ADFD-PIC) is presented for code division multiple access transmission, which not only combats the intersymbol interference and multiple access interference but also suppresses other-cell interference. For frequency-selective smoothly time-varying channels, the proposed ADFD-PIC structure using the erasure algorithm based soft-slicer and channel estimator (EC-ADFD-PIC) offers performance improvement by mitigating the adverse effects of error propagation. The simulation results are presented to demonstrate the substantial improvement in bit error rate performance of the minimum mean square error EC-ADFD-PIC over other multiuser detection techniques.
