an optimum BPSK receiver in AWGN channel (4 votes, average: 5.00 out of 5) Loading... BPSK modulation is the simplest of all the M-PSK techniques. An insight into the derivation of error probability of error for bpsk and qpsk rate performance of an optimum BPSK receiver is essential as it serves
Bit Error Rate Matlab Code
as a stepping stone to understand the derivation for other comparatively complex techniques like QPSK,8-PSK etc.. Understanding the ber of bpsk in awgn channel matlab code concept of Q function and error function is a pre-requisite for this section of article. The ideal constellation diagram of a BPSK transmission (Figure 1) contains two constellation points located https://www.mathworks.com/matlabcentral/fileexchange/9236-bpsk-probability-of-error-in-awgn equidistant from the origin. Each constellation point is located at a distance $latex \sqrt{Es} $ from the origin, where Es is the BPSK symbol energy. Since the number of bits in a BPSK symbol is always one, the notations – symbol energy (Es) and bit energy (Eb) can be used interchangeably (Es=Eb). Assume that the BPSK symbols are transmitted through an http://www.gaussianwaves.com/2012/07/intuitive-derivation-of-performance-of-an-optimum-bpsk-receiver-in-awgn-channel/ AWGN channel characterized by variance = N0/2 Watts. When 0 is transmitted, the received symbol is represented by a Gaussian random variable ‘r' with mean=S0 = $latex \sqrt{Es} $ and variance =N0/2. When 1 is transmitted, the received symbol is represented by a Gaussian random variable – r with mean=S1= $latex \sqrt{Es} $ and variance =N0/2. Hence the conditional density function of the BPSK symbol (Figure 2) is given by, Figure 1: BPSK - ideal constellation Figure 2: PDF of BPSK Symbols $latex \begin{matrix} f(r\mid 0_T)=\frac{1}{\sqrt{\pi N_0}}exp\left \{ -\frac{\left( \hat{r}-\hat{s}_0\right )^2}{N_0} \right \} \;\;\;\;\;\rightarrow (1A) \\ \\ f(r\mid 1_T)=\frac{1}{\sqrt{\pi N_0}}exp\left \{ -\frac{\left( \hat{r}-\hat{s}_1\right )^2}{N_0} \right \}\;\;\;\;\;\rightarrow (1B) \end{matrix} &s=1&fg=0000A0$ An optimum receiver for BPSK can be implemented using a correlation receiver or a matched filter receiver (Figure 3). Both these forms of implementations contain a decision making block that decides upon the bit/symbol that was transmitted based on the observed bits/symbols at its input. Figure 3: Optimum Receiver for BPSK When the BPSK symbols are transmitted over an AWGN channel, the symbols appears smeared/distorted in the constellation depending on
