“…The channel matrix of (1) is rewritten as H = H R 1/2 , where H is the uncorrelated channel H in (1), while R is the channel correlation matrix at the transmitter. It is common in the literature [3,13,19] to employ the simple correlation matrix with elements , = | − | where and are indexes of TAs in a linear array and ∈ [0, 1]. Figure 8 illustrates the effect of the correlation coefficient on the BER at / = 12 dB.…”

“…This approach develops algorithms to find the TPC codeword that realizes a design objective for the given CSI [12][13][14][15][16][17][18][19][20]. This algorithm should be used in the transmitter and receiver to yield the same codeword, and it requires full knowledge of the CSI at both sides.…”

“…Besides, huge overhead is required to obtain full CSI through feedback with infinite rate, particularly in the Frequency Division Duplex (FDD) systems [21]. To solve this latter problem, the research in [19] suggests quantizing the channel phase angles at the receiver, and feeding them back to the transmitter with limited number of bits, to be used for phase compensation at the transmitter. Also, [20] proposes a simplified power allocation method.…”

This paper considers codebook-based precoding for Space Shift Keying (SSK) modulation MIMO system. Codebook-based precoding avoids the necessity for full knowledge of Channel State Information (CSI) at the transmitter and alleviates the complexity of generating a CSI-optimized precoder. The receiver selects the codeword that maximizes the Minimum Euclidean Distance (MED) of the received constellation and feeds back its index to the transmitter. In this paper, we first develop a new accurate closed-form Bit Error Rate (BER) for SSK without precoding. Then, we investigate several phase-rotation codebooks with quantized set of phases and systematic structure. Namely, we investigate the Full-Combination, Walsh-Hadamard, Quasi-Orthogonal Sequences, and Orthogonal Array Testing codebooks. In addition, since the size of the Full-Combination codebook may be large, we develop an iterative search method for fast selection of its best codeword. The proposed codebooks significantly improve the BER performance in Rayleigh and Nakagami fading channels, even at high spatial correlation among transmit antennas and CSI estimation error. Moreover, we show that only four phases {+1, + , −1, − } are sufficient and further phase granularity does yield significant gain. This avoids hardware multiplication during searching the codebook and applying the codeword.

Abstract-In this paper, Multi-Stream Receive-Spatial Modulation (MSR-SM) for application to the Multiple-Input MultipleOutput (MIMO) broadcast channel is introduced and studied. MSR-SM is a closed-loop transmission scheme, which applies the concept of multi-stream space modulation at the receiver side. An accurate mathematical framework for the evaluation of the Bit Error Rate (BER) is proposed. In addition, the diversity order and coding gain of the new architecture are derived. Note that the proposed analytical framework takes into account both the smallscale fading and the system topology, and is directly applicable to the conventional MIMO broadcast channel. Compared with the state-of-the-art MIMO transmission in the broadcast channel, it is mathematically shown that MSR-SM achieves the same diversity order and a better coding gain, in the high Signal-toNoise Ratio (SNR) regime. Finally, the proposed mathematical framework and the new findings are validated via Monte Carlo simulation results.

“…As a result, the conventional SM is only applicable to specific TA configurations associated with log 2 (N t ) being an integer. Recently, the issues of spatial constellation optimization, hybrid bit-to-symbol mapping, link adaptation, and constellation randomization were investigated in [9]- [16], which were applied to single-RF SM. However, the above-mentioned refined transceiver designs still remain unsuitable for an arbitrary number of TAs associated with a single RF.…”
