“…For example, lattice-based space-time block codes were studied in [3] to exploit the advantages of SSD for further performance improvement. In [4], [5], bit-interleaved coded modulation (BICM) combined with coordinate interleaving and rotated constellations to double the diversity order was demonstrated. Further work on BICM with iterative decoding (BICM-ID) in [6] examined symbols in the two-dimensional signal space.…”

Abstract-This paper presents a performance analysis of bitinterleaved coded-modulation with iterative decoding (BICM-ID) and complex N -dimensional signal space diversity in fading channels to investigate its performance limitation, the choice of the rotation matrix and the design of a low-complexity receiver. The tight error bound is first analytically derived. Based on the design criterion obtained from the error bound, the optimality of the rotation matrix is then established. It is shown that using the class of the optimal rotation matrices, the performance of BICM-ID systems over a Rayleigh fading channel approaches that of the BICM-ID systems over an AWGN channel when the dimension of the signal constellation increases. Furthermore, by exploiting the sigma mappings for M -QAM constellations, a very simple suboptimal, but yet effective iterative receiver structure suitable for signal constellations with large dimensions is proposed. Simulation results in various cases and conditions indicate that the proposed receiver can achieve the analytical performance bounds with low complexity.

“…Recent progress has been made for the multiple antenna case by optimizing STCs for fast fading [15]- [17] or by applying the idea of I-Q (inphase and quadrature component) interleaving to STCs [18], [19]. We will not investigate the latter method because it also increases diversity in bit-based coding [20]. The question remains as to whether or not STCs are an appropriate channel coding class for fast(er) fading scenarios or for OFDM.…”

“…From simulation results, we later conclude that BICM outperforms STCs because BICM relies on binary codes instead of being signal-space codes like STCs. With comparable code trellis complexity, BICM achieves larger Hamming distances [20], which are beneficial in fast fading scenarios. Further, a larger flexibility in rate adaptation is achieved, which is desirable in packet data communication.…”

Abstract-Multiple-antenna channel coding for orthogonal frequency-division multiplexing (OFDM) transmission over dispersive channels is reconsidered because with frequency interleaving, the effective channel characteristic across subcarriers is rather fast fading. The channel does not comply with the quasistatic model widely assumed for space-time trellis codes (STCs). For that reason, we first study the ideal fast-fading multiple transmit and receive antenna channel and then compare the performance of STCs with that of bit-interleaved coded modulation in fast fading. Mutual information of the ergodic channel is evaluated for numerous modulation scenarios, and capacity comparisons generate guidelines on how to jointly adjust coding rate and modulation cardinality. Bit-based coding offers large flexibility in rate adaptation, and simulation results show that it outperforms STCs in ideal fast fading and, finally, in a realistic OFDM application as well.

“…Also, in [5] it was shown that for a block independent wireless communication link, improved performance can be obtained for a QPSK system without effecting its bandwidth efficiency, by rotating the signal constellation and separately interleaving the in-phase (I) and quadrature phase (Q) components. In [6], [7], this approach was used to improve the performance by combining with BICM. In [6] and [7], convolutional codes in a BICM system using coordinate interleaving were shown to have improved performance not only over conventional BICM system but also over trellis coded modulation (TCM).…”

Abstract-Bit interleaved coded modulation (BICM) schemes have been shown to increase the diversity order. This paper studies the extension of such schemes with iterative demodulation and decoding (ID) using error correcting codes coupled with rotated MPSK signal constellations with different symbol mappings and signal space diversity (SSD). Using extrinsic information transfer (EXIT) charts, an analysis of the impact of the rotation angle on the performance of the system is presented. It is shown that for a given signal constellation, labeling, error correcting code and E b /N0-value, where conventional BICM-ID system's decoding trajectory gets stuck in a Rayleigh fading channel, SSD with a well considered choice of the rotation angle allows for the convergence of iterative demodulation and decoding. Furthermore, it is shown that the proposed system can lead to a significant performance gain over BICM-ID. The optimal choice of the rotation angle for the coded system is shown to be dependent upon the signal labeling and the error correcting code being employed. Factors (degrees of freedom) that can effect the convergence behavior of the iterative demodulation and decoding of the proposed system are identified and their effect is analyzed.
