WebAug 5, 2007 · Yes, for BPSK the noise component on the imaginary arm is ignored. To make the noise model same as with other modulation schemes, I kept it as complex. 2). The division by 20 is to convert the dB to scale the voltage signal. In my simulation model, the noise term n is a Gaussian random variable with mean 0 and variance 1.
WebJan 8, 2016 · Since BPSK transmits one bit per symbol, and the symbol rate is 1 T, BPSK can transmit 1 T bits per second. Therefore, the bit rate divided by the bandwidth is 1 T 2 T, which reduces to 1 2. Thus, the bit rate is 1 2 the bandwidth.
