摘要：The growing demand for capacity in wireless communications is the driving force behind improving established networks and the deployment of new worldwide mobile standard. Multiple Access Interference (MAI) and Inter Symbol Interference (ISI) limit the capacity of the system. The conventional approaches for wireless communication may not be good in many ways. Here, a proposal has been given to show that the problems in conventional approaches may be avoided, if the proposed Parallel Interference Cancellation (PIC) multi user detection with feedback (PICF MUD) is adopted in various multiple access schemes. In DS-CDMA system using PIC receiver with four stages, the Eb/No required to achieve a BER performance of 10-3 is 8 dB, whereas the single stage PIC receiver with feedback approach requires only 2 dB to achieve the same BER. The proposed PICF MUD is extended in various multiple access systems to provide better BER performance.
