– In this paper we propose an iteratively detected The employment of joint source and channel coding techniques has been motivated by the fact that the classic Shannonian source and channel coding separation theorem [1] has limited applicability in practical speech systems [2]. This is due to the delay-and complexity constraints of practical speech(More)
This paper presents a novel differentially encoded space-time spreading (DSTS) scheme using four transmit antennas that can be readily combined with PSK, QAM, as well as sphere packing (SP) modulation schemes. The advocated SP-aided system has simple encoding and decoding algorithms that requires no channel knowledge and outperforms the DSTS dispensing with(More)
