Abstract :
The detectability of the symbol rate of an offset quadrature-modulated signal by a delay and multiply receiver is investigated. Signal pulses considered are filtered rectangular pulses. The signal-to-noise ratio (SNR) at the receiver output is used as the measure of detectability. The effects of timing error, amplitude balance and filter order are studied. Also, analytical results are compared with results from computer simulation. It is observed that filtered rectangular pulses with offset quadrature modulation can give very low rate line SNR
