Abstract :
The performance of a low complexity correlation receiver for a rate variable SQAM modem is analytically and experimentally studied. It is found that the proposed receiver performs well for a range of SQAM signals 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 power limited satellite broadcasting systems such as a data broadcasting USAT (ultra small aperture terminal) network
