一种新的全分集准则和低复杂度部分干扰抵消译码空时分组码

A New Full-diversity Criterion and Low-complexity STBCs with Partial Interference Cancellation Decoding

Lakshmi Prasad Natarajan, B. Sundar Rajan

摘要:

最近,Guo和Xia给出了在接收端使用PIC(Partial Interference Cancellation,部分干扰消除)或PIC-SIC(PIC with Successive Interference Cancellation,连续干扰消除)解码器时空时分组码实现全分集的充分条件。在本文中,我们给出了替代条件的STBC实现全分集PIC和PIC-SIC解码器,这是等价的郭和夏的条件,但更容易检查。利用这些条件,我们构造了一类新的全分集PIC-SIC可译码码,它包含了Toeplitz码和Zhang,Xu等人最近提出的一类码。作为适当的子类。借助于新的准则,我们还证明了最近由Zhang,Shi等人提出的一类PIC-SIC可译码码。可以以比所报告的复杂度低得多的复杂度来解码,而不损害全分集。

英文摘要:

Recently, Guo and Xia gave sufficient conditions for an STBC to achieve full diversity when a PIC (Partial Interference Cancellation) or a PIC-SIC (PIC with Successive Interference Cancellation) decoder is used at the receiver. In this paper, we give alternative conditions for an STBC to achieve full diversity with PIC and PIC-SIC decoders, which are equivalent to Guo and Xia's conditions, but are much easier to check. Using these conditions, we construct a new class of full diversity PIC-SIC decodable codes, which contain the Toeplitz codes and a family of codes recently proposed by Zhang, Xu et. al. as proper subclasses. With the help of the new criteria, we also show that a class of PIC-SIC decodable codes recently proposed by Zhang, Shi et. al. can be decoded with much lower complexity than what is reported, without compromising on full diversity.
