The bit error rate (BER) performance loss of M -ary differential phase-shift keying (MDPSK) with respect to M -ary phase-shift keying (MPSK) in wireless fading channels has been extensively studied, but the understanding on this problem in lognormal fading channels has been limited. The most recent work showed the asymptotic BER performance losses of BDPSK and QDPSK with respect to BPSK and QPSK, respectively, in the lognormal fading channels. However, it is not known how the modulation order increases. In this paper, we derive the general expression of the relative BER performance loss of MDPSK with respect to MPSK for arbitrary M over the lognormal fading channels in high signal-to-noise ratio regimes. We start our analysis by investigating the asymptotic BER performance losses of MDPSK with respect to MPSK for M = 4, 8, and 16. Using the regularity of these results, we obtain the general closed-form expression of the relative BER performance loss in the lognormal fading channels.Index Terms-Lognormal fading channels, M -ary differential phase-shift keying (MDPSK), M -ary phase-shift keying (MPSK). 0018-9545 (c)

“…On the contrary, M-DPSK with differentially coherent detection can be adopted with a sacrifice of some performance without channel state information at the receiver. In addition, it is well-known that M-PSK has 3.01dB performance advantage over M-DPSK in Rayleigh fading channels [8]. Thus, to analytically evaluate the performance loss of M-DPSK with respect to M-PSK over Rician-Nakagami fading channels, we calculate the following asymptotic SER performance loss (in dB) of M-DPSK w.r.t.…”

“…Therefore, in this paper, we attempt to derive more effective and simpler closed-form SER expressions for both M-PSK and M-DPSK modulation schemes, which are based on the existing formulas given in [6]. Furthermore, it is well-known that 3.01dB performance gain can be achieved by M-PSK over M-DPSK in Rayleigh fading channels [8]. Thus, by deriving the formulas for the achievable modulation gains of M-PSK and M-DPSK, we also evaluate the SER performance loss of M-DPSK with respect to M-PSK for any modulation order M at high signalto-noise ratio (SNR) in Rician-Nakagami fading channels.…”

Using the existing exact but quite complicated symbol error rate (SER) expressions for M-ary phase shift keying (M-PSK) and M-ary differential phase shift keying (M-DPSK), we derive effective and concise closed-form asymptotic SER formulas especially in Rician-Nakagami fading channels. The derived formulas can be utilized to efficiently verify the achievable error rate performances of M-PSK and M-DPSK systems for the Rician-Nakagami fading environments. In addition, by exploiting the modulation gains directly obtained from the asymptotic SER formulas, we also theoretically demonstrate that M-DPSK suffers an asymptotic SER performance loss of 3.01dB with respect to M-PSK for a given M in Rician-Nakagami fading channels at high signal-to-noise ratio (SNR).

“…When the required CSI cannot be tracked accurately, binary differential phase-shift keying (DPSK) is an attractive alternative with inferior BER performance. It is well-known that DPSK is 3 dB worse than BPSK in Rayleigh channels in high SNR regimes [10]. One fundamental question we aim to answer is what the performance loss of DPSK with respect to (w.r.t.)…”

Abstract-Using an auxiliary random variable technique, we prove that binary differential phase-shift keying and binary phase-shift keying have the same asymptotic bit-error rate performance in lognormal fading channels. We also show that differential quaternary phase-shift keying is exactly 2.32 dB worse than quaternary phase-shift keying over the lognormal fading channels in high signal-to-noise ratio regimes.
