此篇論文提出了一種使用於快跳頻多址進接結合複頻鍵移多存取(FFH/MFSK MA)系統利用遞迴式消去多用戶干擾 (iterative multi-user interference cancellation) 的方式。這種類似渦輪 (Turbo) 解碼的方式結合了多用戶檢測接收機 (multi-user detector) 與軟輸入輸出的通道解碼器 (SISO channel decoder)。這兩個元件相互地交換軟資訊，由多用戶檢測接收機提供的資訊用來驅動後一級的通道解碼器；而通道解碼器則提供暫態的決定 (tentative decisions) 給多用戶檢測接收機用以消去多用戶干擾。和傳統的封包檢測器 (envelope detector) 不同，這一篇論文將封包檢測器的輸出分成三種不同的值。這種方式在可加性高斯雜訊 (AWGN)、瑞雷 (Rayleigh) 與萊斯 (Rician) 通道下的效能將呈現在最後的模擬結果。

An iterative multi-user detection based on Turbo principle is proposed to reduce the BER in convolutional coded fast frequency hopping multiple access (FFH/MFSK MA) systems. The proposed algorithm for the multi-user detector is an iterative interference cancellation (IIC) scheme which is composed of a bank of soft-input soft-output (SISO) channel decoders. The soft reliable information is exchanged iteratively between the proposed multi-user detector and the SISO channel decoders. In the multi-user interference cancellation process, a three-value cancellation mechanism instead of conventional two-value one is also proposed to further improve the system performance. Such performance improvement is validated by the system simulations in this thesis.
