We propose an adaptive scheme of a differential codebook for temporally correlated channels. And the codeword entries of the propose codebook are selected among the set of M-PSK constellations -the values of M proposed in this paper are 8, 16, or 32. Firstly, we analyze mathematically how the optimal spherical cap radius of the proposed codebook is tracked. Then, we explain the practical implementation of the proposed adaptive method. Practically, some candidate differential codebooks we propose in this paper can be switched according to the temporal correlation coefficients of wireless channels in the proposed scheme. Monte-Carlo simulations demonstrate that the achievable throughput performance employing the proposed codebook is always superior to those of the differential codebooks employing M-PSK constellations and non-adaptive differential codebooks with the same amount of feedback information. . 제한된 피드백 통신은 채널 공간의 양자화 왜곡 (332)

“…In [16] and [17], was proposed a combination lock-like differential codebook or called the M -phase shift keying (PSK) differential codebooks based on MIMO systems in which only M -PSK constellations are exploited for computational simplicity and perfect compatibility with LTE release-8 codebook design criteria [18]. In this paper, we propose an adaptive method by adaptively switching M -PSK differential codebooks according to the temporal correlation coefficients at every time instant.…”

We propose an adaptive scheme of a differential codebook for temporally correlated channels. The codeword entries of the proposed codebook are selected among the set of M -PSK constellations and the values of M proposed in this paper are 8, 16, or 32. Firstly, we analyze mathematically how the optimal spherical cap radius of the proposed codebook is tracked. Then, we explain how to implement the proposed differential equal-gain codebook practically. Among the candidate differential codebooks designed for various temporal correlation coefficients, the proper codebook can be chosen (or switched) according to the temporal correlation coefficients of wireless channels. We assume that the correlation coefficients of the channels are known to the receiver and the properly (or optimally) chosen differential codebook can show the best system throughput performance. Monte-Carlo simulations demonstrate that the achievable throughput performance employing the proposed codebook is always superior to those of the differential codebooks employing M -PSK constellations and non-adaptive differential codebooks with the same amount of feedback information.
