“…Since T is a TCM, in the remainder of this section, we will consider the pairwise error probability (PEP), P (z →z ), that the maximum likelihood (ML) decoder decides in favor of the codewordz instead of the transmitted codewordz for the case of TCM. The cases of BICM in MIMO and MIMO-OFDM systems can be found in [6] and [7][8], respectively.…”

“…In this paper, serial concatenated STBC with T is investigated for both quasi-static and fast fading channels as in the case of [1][2] [6]. Although a convolutional interleaver is used in T , in this paper, we show that the error performance of concatenated STBC with T can be improved significantly for fast fading channels by inserting a specific block interleaver between the encoders of T and STBC.…”

“…In [1] [2], serial concatenated STBC [4] with Ungerboeck's TCM was investigated. The cases of BICM and TTCM were investigated in [6] and [25], respectively. In [9][10], a TCM with a delay processor, denoted by T , was proposed to achieve large free Euclidean distances, where the delay processor is a kind of convolutional interleaver [19].…”

It is known that tail-biting codes T constructed from trellis coded modulation (TCM) with a delay processor can achieve large minimum Euclidean distances. In this paper, concatenated space-time block coding (STBC) with T for multiple-input multiple-output (MIMO) and MIMO-OFDM (orthogonal frequency-division multiplexing) systems is investigated. We propose an improved system which is implemented by inserting a specific block interleaver between the encoders of coded modulation and STBC. We also propose sliding-windowtype iterative decoding using partial hard-decision feedback (SW-IDPHF) with low complexity to decode T , which provides better error performance as compared to sliding-window-type iterative decoding using full hard-decision feedback (SW-IDFHF). In addition, we apply sliding-window-type iterative decoding using soft-decision feedback (SW-IDSF) to T for improved error performance. The decoder of concatenated system based on T can converge faster and provide better ultimate error performance as compared to the case of BICM under various channel conditions for either MIMO or MIMO-OFDM systems.Index Terms-Space-time code, diversity, trellis coded modulation (TCM), bit-interleaved coded modulation (BICM), multipleinput multiple-output (MIMO) systems, orthogonal frequencydivision multiplexing (OFDM) systems.

“…In the case of coherent MIMO communication systems, several numerically optimized mappings have recently been proposed [11], [19], [20], but the Grassmannian geometry of our constellation for the non-coherent case means that a different mapping is required. We will use a rather simple mapping based on a straight forward application of (incomplete) set partitioning [21].…”

A bit-interleaved coded modulation (BICM) scheme with iterative demapping and decoding (ID) is developed for non-coherent communication over a multiple-input multipleoutput (MIMO) channel. The scheme exploits the underlying Grassmannian geometry of the signalling scheme that achieves the ergodic capacity of the non-coherent model at high signal-tonoise ratios. In particular, this geometry gives rise to an efficient list-based demapping algorithm that substantially reduces the computational complexity of the receiver. By allowing the decoder to augment the demapping list, the performance degradation of this efficient algorithm can be rendered insignificant. We compare the performance of the proposed scheme with that of a training-based BICM-ID scheme and show, via simulation, that the proposed scheme can provide significantly better performance at high data rates.

“…BICM has been concatenated with orthogonal space-time block codes (OSTBCs) to harvest temporal and spatial diversities in flat fading channels [3], [4], and has also been used in conjunction with orthogonal frequency division multiplexing (OFDM) to exploit frequency diversity [5], [6]. Recently, BICM is combined with OSTBC-OFDM and it was shown in [5] that the distributed BICM-OSTBC-OFDM system is able to extract both the spatial and frequency diversities in independent and identically distributed (i.i.d.)…”

-Maximum spatial-frequency diversity can be achieve by combining bit-interleaved coded modulation (BICM), orthogonal space-time block coding (OSTBC) and orthogonal frequency division multiplexing (OFDM) in frequency selective multi-path fading channels, provided that perfect channel state information (CSI) is available to the receiver. In view of the fact that perfect CSI can be obtained only if a sufficient amount of resource is allocated for training or pilot data, this paper investigates DF relay based technique for the distributed BICM-OSTBC-OFDM system. Our focus is mainly on noncoherent diversity analysis. We study a class of carefully designed transmission schemes, called perfect channel identifiability (PCI) achieving schemes, and show that they can exhibit good diversity performance. Specifically, we present a worst-case diversity analysis framework to show that PCI-achieving schemes can achieve the maximum noncoherent spatial-frequency diversity of distributed BICM-OSTBC-OFDM. Simulation results are presented to confirm our theoretical claims and show that the proposed noncoherent schemes can exhibit near-coherent performance.
