Performance analysis of space modulation techniques over α − μ and κ − μ fading channels with imperfect channel estimation

Abstract

In this paper, the performance analysis of spatial modulation and space shift keying multiple‐input multiple‐output techniques over generalised α − μ and κ − μ fading channels with imperfect channel state information at the receiver is presented. In particular, the pair‐wise error probability (PEP) of the systems under study is derived. The PEP expression jointly considers the envelope and the phase distributions of the fading channels. The obtained PEP is then used to derive an upper bound closed‐form expression for the average bit error rate. The influence of the fading parameters (i.e. α,κ and μ) and the channel estimation error on the system performance are analysed and discussed through representative numerical examples. The correctness of the conducted analysis is validated by means of Monte‐Carlo simulations. Copyright © 2015 John Wiley & Sons, Ltd.

Performance Analysis of Spatial Modulation Under Rapidly Time-Varying Rayleigh Fading Channels

“…Considering now (35) in (21) gives (39) and then (37) and the average PEP for this error case can be given by…”

“…SM has gained huge endeavor in communication systems research community, especially, in studying its average bit error probability (ABEP) performance over wireless multipath fading channels, for e.g., [3], [9]- [21]. A careful literature survey confirms that most existing works focus on evaluating the SM systems' ABEP performance assuming quasi-static fading channels, i.e., the channel temporal characteristics are assumed to be invariant for a relatively long time.…”

Performance analysis ofL‐branch maximal ratio combining over generalisedη−μfading channels with imperfect channel estimation

“…In practical system, the channel α ℓ is not known at the receiver, and a channel estimation algorithm is used to obtain an estimate channelâ ℓ . The channel estimation error is defined as [18,19] a ℓ = a ℓ + e.…”

“…However, it is straightforward to show that the parameters of the Fox's H-function in (19) and (35) satisfy these sufficient conditions, and therefore the Fox's H-function converges (see (18)(19)(20))…”

Performance analysis of SFBC‐OFDM system with channel estimation error over generalized fading channels

“…A lot of work has been done on the performance analysis of SFBC‐OFDM system over different fading channels. () In the year 2002, Lu et al proposed a low‐density parity‐check code–based space‐time code OFDM system for correlated fading channels in which performance analysis was given in terms of outage probability and OFDM word error rate. The frame error rate and outage probability of binary phase‐shift keying (BPSK) and quadrature phase‐shift keying (QPSK) modulated space‐time block code (STBC)–based and SFBC‐based OFDM system was reported by El Gamal et al The performance analysis of space‐time coding was done in the work of Garg et al with imperfect channel estimation in 2005.…”
