Chapter 7 introduces the other two space - time codes besides space - time block codes - space - time trellis codes and space - time layered codes 第七章简单介绍了除空时分组码之外的两大类空时码,空时格状码和分层空时码。
After reviewing compression algorithms in sar , the author introduces a new compression algorithm : trellis coded quantization ( tcq ) 论文在回顾了以往sar使用的原始数据压缩算法后,引入了一种新的数据压缩编码算法:栅格编码量化( tcq ) 。
In chapter 4 , space - time trellis coding ( sttc ) is studied . an exact pairwise error probability is derived for space - time codes operating over rayleigh fading channels 在第四章中,研究了空时格状编码的问题,推出了误码概率的确切表达式。
At last , conclusions are drawn on these algorithms . based on scalar quantization of chapter 2 , chapter 4 introduces trellis coded quantization to improve quantization gain 第四章是在第二章标量量化的基础上引入网格编码量化的方法以进一步提高量化增益。
But for the same reason , it have n ' t the same diversity feature as space - time block code , as well as it have n ' t the same error correction capability as convolutional code or trellis code modulation 由于空时格码兼顾了分集和信道编码,导致其分集特性不如空时分组码,纠错能力不如卷积码和格形编码调制。
