Instead of an optical 90 degrees -hybrid, a 3*3 fibre coupler and a signal processing … WebANSWER : Bits per seconds is equals to twice the baud rate of a QPSK since the rate of change of the output signal is one half of the input rate of change of the input signal . 14.QUESTION: Explain the significance of the I and Q channels in a QPSK modulator. ANSWER : The I channel represents the in phase signal which is represented by while ...
WebNov 7, 2011 · In pass-band communication, the minimum required bandwidth for a transmission rate of Rs symbol/s is Rs (assuming rectangular pulse shape). In BPSK the symbol rate is the same as the bit rate, i.e.: Rs=Rb. So, the minimum required bandwidth for BPSK is WB=Rb. For QPSK, Rs=Rb/2, so WQ=Rb/2. WebIt is interesting to note that for higher order M-PSK, this 3 dB result does match (note the difference between QPSK and DQPSK in the plot above). Perhaps this is a clue that real versus complex is a factor?
