of quadriphase shift keying in the presence of additive white Gaussian noise and a Tikhonov distributed-phase-reference error. The accuracy qam symbol error rate of the approximation is verified via actual numerical integration of the bit-error-probability formula. The approximation is easy to compute, and shows correctly the behaviour of the bit-error probability as a function http://ieeexplore.ieee.org/iel4/2191/10509/00488012.pdf?arnumber=488012 of the signal-to-noise ratio. In particular, it shows that, for high signal-to-noise ratios, the bit-error probability behaves as the reciprocal of the square root of the formerDo you want to read the rest of this article?Request full-text CitationsCitations23ReferencesReferences4Simplified bit error rate evaluation of Nagakami‐m PSK systems with phase error recovery"Since exact evaluation is usually complex, the BER of nonideal PSK systems was https://www.researchgate.net/publication/3349809_Bit-error_probability_of_QPSK_with_noisy_phase_reference obtained by numerically integrating the conditional BER expression for a fixed phase error over the phase error statistic [5,11]. Later on, many authors have devoted this problem by using infinite series approaches [12,13], giving approximate solutions [6,8], and [9], or deriving upper and lower bounds [7,12], and [10]. The previous studies did not take channel fading into account, a phenomenon important in wireless communications. "[Show abstract] [Hide abstract] ABSTRACT: An efficient analytical and simulation techniques were developed to analyze the bit error rate of PSK Nakagami-m fading systems with imperfect carrier recovery. We evaluate the detection loss due to the carrier recovery for different rms phase error values when coherent BPSK and QPSK systems are used in wireless channels. Our results are useful in designing practical systems and will enable designers to determine the phase precision of PSK systems in wireless environments. Copyright © 2010 John Wiley & Sons, Ltd.

In this post, we will derive the theoretical equation for bit error rate (BER) with Binary Phase Shift Keying (BPSK) modulation scheme http://www.dsplog.com/2007/08/05/bit-error-probability-for-bpsk-modulation/ in Additive White Gaussian Noise (AWGN) channel. The BER results obtained using Matlab/Octave simulation scripts show good agreement with the derived theoretical results. With Binary Phase Shift Keying (BPSK), the binary http://www.mathworks.com/help/comm/ref/berawgn.html digits 1 and 0 maybe represented by the analog levels and respectively. The system model is as shown in the Figure below.

The first input argument, EbNo, is the ratio of bit energy to noise power spectral density, in dB. If EbNo is a vector, the output ber is a vector of the same size, whose elements correspond to the different Eb/N0 levels.
