    A microwave line of sight link has a single hop.. The link has an RF channel with a bandwidth 10 MHz. The transmitter and receiver have ideal RRC filters with
    ? = 0.25.

    a. What is correct symbol rate (pulse rate) for this link?

    b. What is the bit rate with BPSK modulation?

    c. What is the bit rate with QPSK modulation?

    d. What is the noise bandwidth of the receiver?

    a. Use the equation

    B = (1 + r)*SR where SR = SYMBOL RATE, r = filter rolloff = 0.25, B = 10 MHz = bandwidth

    Putting in ...
