【摘要】 本文研究了线性码编码的MSK调制系统。指出在插入一个简单差分编码网络后,线性码的优化问题在汉明距离与在欧氏距离上是一致的,从而解决了线性码编码的MSK调制问题。由于插入网络简单、便于实现,因此在MSK上使用最优线性码调制在实践上是可行的。更多还原

【Abstract】 MSK modulation coded by linear codes is studied in the paper. It shows that, by cascading a differential coding network, the optimization of a linear code (block or convolutional) in its Hamming distance is the same as in the Euclidean distance of its modulated sequences. In this sense, the problem of coded modulation for MSK is completely solved for linear codes.更多还原
