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