LOW-COMPLEXITY CORRELATION RECEIVER FOR RATE VARIABLE SQAM MODEM

The performance of a low complexity correlation receiver for a rate va riable SQAM modem is analytically and experimentally studied. It is fo und that the proposed receiver performs well for a range of SQAM signa ls by adjusting the amplitude parameter 'B' of the receive correlation pulse. The authors demonstrate that the suggested SQAM receiver would be very well suited for use in low cost as well as bandwidth and powe r limited satellite broadcasting systems such as a data broadcasting U SAT (ultra small aperture terminal) network.
