Abstract :
This correspondence describes staggered quadrature overlapped squared raised-cosine (QOSRC) modulation. The power spectrum of QOSRC attains good spectral characteristics over a bandpass hardlimited channel compared to quadrature overlapped raised-cosine (QORC) modulation because of less fluctuation of the signal envelope. It is found that QOSRC has better bit error probability performance than QORC.
