Differential Space-Time Spreading using Iteratively Detected Sphere Packing Modulation and Two Transmit Antennas
Differential Space-Time Spreading using Iteratively Detected Sphere Packing Modulation and Two Transmit Antennas
A novel Differentially encoded Space-Time Spreading (DSTS) scheme using two transmit antennas and Sphere Packing (SP) is proposed, which we refer to as the DSTS-SP arrangement. The advocated SP-aided system outperforms DSTS dispensing with SP and requires no channel knowledge. We also demonstrate that the performance of DSTS-SP systems can be further improved by serially concatenated convolutional coding and by performing SP-symbol-to-bit demapping as well as channel decoding iteratively. Explicitly, the proposed turbo-detected DSTS-SP scheme exhibits an Eb/N0 gain of 17.8dB at a Bit Error Rate (BER) of 10?5 over an uncoded identical-throughput system and an Eb/N0 gain of 1.9dB over the equivalent 2 bits/symbol effective throughput QPSK-modulated turbo-detected DSTS scheme.

Abstract
A novel Differentially encoded Space-Time Spreading (DSTS) scheme using two transmit antennas and Sphere Packing (SP) is proposed, which we refer to as the DSTS-SP arrangement. The advocated SP-aided system outperforms DSTS dispensing with SP and requires no channel knowledge. We also demonstrate that the performance of DSTS-SP systems can be further improved by serially concatenated convolutional coding and by performing SP-symbol-to-bit demapping as well as channel decoding iteratively. Explicitly, the proposed turbo-detected DSTS-SP scheme exhibits an Eb/N0 gain of 17.8dB at a Bit Error Rate (BER) of 10?5 over an uncoded identical-throughput system and an Eb/N0 gain of 1.9dB over the equivalent 2 bits/symbol effective throughput QPSK-modulated turbo-detected DSTS scheme.
