PERFORMANCE OF STAGGERED QOSRC MODULATION ON A HARD-LIMITED SATELLITE CHANNEL IN THE PRESENCE OF UPLINK AND DOWNLINK NOISE AND INTERSYMBOL INTERFERENCE

摘要

The average bit error probability performance of staggered QOSRC modulation on a hard-limited satellite channel in the presence of uplink and downlink noise and intersymbol interference caused by transmit filtering is analyzed.We derive the expression of the bit error probability of staggered QOSRC in the case of no intersymbol interference. And further, the effect of intersymbol interference is considered by using the computational techniques based on moments of interferences. It is found that the staggered QOSRC has superior bit error probability performance compared to staggered QORC.
