golay
解釋
戈萊-
3. we propose a new spreading sequence design scheme. in the uplink, using golay sequence, cinew sequence or zadoff - chu sequence, in the downlink, using wh sequence as the spreading sequence, we can control the papr of mc - cdma below 7db and ber below le - 3 ( snr = 20db )
提出mc - cdma中擴頻序列的新型設計方案，在上行通道，採用golay序列， cinew序列或zadoff - chu序列，在下行通道，採用wh序列作為擴頻序列可以控制mc - cdma峰平比在7db以內，在信噪比為20db時，系統誤碼率小於1e - 3 。 -
The presented method is shown to be right through computer simulation for the ( 23. 12 ) golay code and the ( 15, 7 ) bch code
對golay碼和bch碼的計算機模擬表明，本文提出的方法是正確的。 -
This thesis researches on reducing the par of mc - cdma from two different points. on one side, this thesis studies behaviors of mc - cdma with golay complementary sequences as spreading sequences
一方面，本文利用格雷互補序列作為mc - cdma信號的擴頻碼，有效降低其峰值平均功率比。 -
Simulation indicates that the par of mc - cdma can be upper bounded 6db by using golay complementary sequences and s - r sequences as spreading sequences, which is much superior to m sequences and hadamard sequences. on the other side of view, compared with the old basic selected mapping method, this thesis proposes some other selected mapping algorithms and compares the performances based analysis and simulation
模擬表明，採用格雷互補序列作為擴頻碼來降低峰平比，不論是效果還是實用性，都大大優于m序列和hadamard序列；另一方面，本文在基本選擇映射演算法基礎上，提出了幾種改進的選擇映射演算法。
