Bit error probability of coherent M -ary PSK over flat Rayleigh fading channels
نویسندگان
چکیده
Systems using coherent multilevel PSK to communicate over flat Rayleigh fading channels are considered. We present a closed-form expression for the exact bit error probability (BEP) when the binary reflected Gray code is used to map bits to symbols. The result is a general, simple, and correct expression, which has not been previously available in the literature. A comparison between this new expression and previous approximate expressions shows that the difference is more significant for fading channels than for Gaussian channels.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملImpact of Uncertain Channel Estimation and Outdated Feedback on the Adaptive M -PSK Modulation
This paper investigates an adaptive M -ary phaseshift keying (M -PSK) modulation scheme over Rayleigh flat fading channels. The data rate is adapted according to the channel state. At the receiver, the fading is estimated using pilot symbols. To cancel the channel impact, we correct the received signal by dividing it by the estimated value of the fading. So, we propose to adjust the modulation ...

| In this paper, we design parallel concatenated convolutional codes (PCCCs) for trellis coded modulation (TCM) over the following discrete two-dimensional (2D) channels: (a) a slow-fading Rayleigh channel with discrete carrier tracking by a phase locked loop (PLL), where the PLL signal-to-noise ratio (SNR) is proportional to the fading amplitude squared; (b) an additive white Gaussian noise (A...

In this paper we present simple closed-form expressions for the probability of error for M-ary phase-shift-key (M-PSK) signaling over a channel with additive white Gaussian noise and nonselective Rayleigh fading. These expressions can be used to analyze the performance of standard uniform M-PSK constellations and nonuniform M-PSK constellations. Nonuniform M-PSK has recently been shown to be us...

In this study, approximate symbol error rate (SER) expressions for M-ary phase shift keying (M-PSK) modulation scheme over independent and identically distributed (i.i.d) slow-flat Rician and Rayleigh fading channels are derived. Simulation results show the superior impact of using the maximum ratio combining (MRC) space diversity technique on the overall performance. In particular, the communi...
