摘要: 在多使用者的無線通訊環境之下,使用者間干擾(Multi-access interference, MAI) 和符號間干擾(Inter-Symbol Interference, ISI)是一直都存在的問題。因為受到多重路徑(Multi-path)的影響,在接收端所收到的訊號,使用着之間的正交性早已消失。對於符號間干擾可以藉由搭配循環前置(Cyclic Prefix, CP)解決,但對於MAI影響,接收機等化器的設計大多以S-DF(Successive interference cancellation Decision Feedback) 以及P-DF(Parallel interference cancellation Decision Feedback)為主,S-DF雖然有不錯的通道容量,但是有使用者間性能不均勻和錯誤蔓延的問題,P-DF系統則是有隨著使用者數上升,系統的設計複雜度也會跟著大幅度上升的問題。因此在本論文提出一個構想,將S-DF和P-DF做一個整合,發展適用於OFDM-CDMA及MC-DS-CDMA系統的連續並行支路干擾消除等化器(Successive Parallel Arbitrated Decision Feedback Detectors, SPA-DF),除了可以預期大幅度改善MAI的問題,更能夠提供更佳的接收機性能。
In multiuser wireless communications system, multi-access interference (MAI) with inter-symbol interference (ISI) is always inevitable. The ISI effect can be eliminated by adding CP before each block in OFDM technology. To dismiss the MAI effect, all existing equalizer algorithm usually use the SIC (Successive Interference Cancellation) algorithms or PIC (Parallel Interference Cancellation) algorithm. SIC algorithm can achieve high channel capacity, but generally leads to non-uniform performance among users. The PIC algorithm complexity is proportional to the number of user. In order to effective relieve the MAI with reasonable complexity, the SIC and PIC algorithms are integrated as Successive Parallel Arbitrated interference canceller with Decision Feedback (SPA-DF), and its performance will be investigated in the uplink of OFDM-CDMA and MC-DS-CDMA systems.
