    Abstract: 位元交錯編碼調變搭配遞迴解碼(bit-interleaved coded modulation with iterative decoding,BICM-ID)是適合於連續衰退通道的通道碼。此外使用相差編碼的BICM-ID,可以避免因前導符號所導致的速率損失,在本論文我們考慮使用16-DAPSK(differential amplitude and phase-shift keying) 的BICM-ID,根據BICM-ID的8-PSK(phase-shift keying)位元標示,我們提出兩種新的位元標示。接著我們對新的位元標示其迴旋碼做籬柵碼搜尋,透過最小距離與模擬結果可以顯示新的位元標示其錯誤效能比原始的相差編碼來得好。在使用新搜尋到的籬柵碼可以進一步改善錯誤效能。;Bit interleaved coded modulation with iterative decoding (BICM-ID) is suitable for continuous fading channels. Besides, BICM-ID using differential encoding can avoid the rate loss due to pilot symbols. In this thesis, we consider BICM-ID using 16-DAPSK (differential amplitude and phase-shift keying). According to the bit labeling of 8-PSK for BICM-ID, we propose two new bit labeling of 16-DAPSK. In addition, convolutional code for the new bit labeling are searched. Both the minimum distance and the simulation results show that the proposed labeling has better error performance than the original differential encoding, and the searched new codes can further improve error performance.
