在IEEE 802.16e-2005 無線通訊標準中訂定了不同類型的前向錯誤更正編碼的機制,其中低密度同位檢查碼( low-density parity-check,LDPC )由於其優異的性能表現日益受到大家注意。本論文中即特別針對802.16e-2005中之LDPC Code進行完整的性能模擬與分析以探討其在行動通訊上的性能表現。
In the IEEE 802.16e-2005 wireless communication standard, different kinds of Forward Error Correction (FEC) coding mechanisms are presented. Particularly, low-density parity-check (LDPC) is getting more and more attention because of its outstanding performance. This thesis especially simulation the complete functions of LDPC Code of 802.16e-2005 and analyses its performance of mobile communication.
