VSAT, frequency re-use,and carrier super-positioning
This paper shows a design approach for signal canceller for carrier super-positioning of VSAT satellite communi cations. The interference caused by the generating error of signal replica for cancellation has been studied in detail for BPSK and QPSK scheme. It is investigated how the phase error between signal and the replica is sensitive to the inter ference. We also propose a method for generating replica very fast by introducing multi-component delay tracking code to measure satellite round trip delay.
