Decoding algorithm for any structure of stbc is derived . the decoding result discovered by tarokh is a special case . then the channel capacity of stbc over rayleigh fading channels is derived 第五章研究了空时分组编码的问题，推导出任意结构的空时分组编码的译码算法， tarokh给出的译码结果可以看作特例。
However , the sequential decoding algorithm is not fully developed because of its complication and limited range of application , which lead to relatively few materials particularly in board 而卷积码的序列译码方法因为其硬件复杂度高和应用范围小,并不十分流行,相关的参考文献也很少,尤其在国内,相关的研究非常少。
There are two decoding schemes for convolution code , such as sequence decoding algorithm and viterbi algorithm . because of simplicity 、 excellent performance , viterbi decoding algorithm is abroad applied 卷积码的译码算法有序列译码和viterbi译码两大类, viterbi译码算法由于其简单、性能优异等特性得以广泛应用。
The viterbi decoding algorithm , proposed in 1967 by viterbi , and it ’ s proved that viterbi decoding algorithm is the maximum likelihood decoder algorithm of convolution code and it has excellent decode performance Viterbi译码算法在1967年由viterbi提出,经证明它是卷积码译码得最大似然译码算法,具有优异的译码性能。
In these years , many new technologies are developed and applied to joint coded modulation systems , such as new error - correcting codes , space - time modulation on mimo channels and iterative decoding algorithm 近年来,随着新的纠错编码、 mimo空时调制以及迭代译码方式的出现,联合编码调制方案的设计正成为普遍关注的热点。
First , the paper briefly introduces theories of convolutional coding , viterbi decoding algorithm and rake receiver . then , the paper focuses on methods to implement viterbi decoder and rake receiver in fpga 本文简要介绍了卷积码、 viterbi译码和rake接收机的原理,详细描述了在fpga中实现viterbi译码和rake接收机的方法。
