Question

Consider a BPSK system operating on an AWGN channel of frequency range [99 MHz, 101 MHz] with 95% in-band power. Suppose that a coherent demodulator is adopted at the receiver and the BER is measured to be 10^-4. 1. Determine the bit rate. (4 marks) 2. If BASK is now used to transmit the bit stream with the same power over the same channel with 95% in-band power. Determine the BER. (10 marks)

Step 1

To determine the bit rate, we need to use the formula: bit rate = bandwidth x log2(M) where M is the modulation scheme, which in this case is BPSK (binary phase shift keying) with two possible symbols (0 and 1). The bandwidth is the frequency range of the Show more…
