SC-FDE with OQPSK-Type Schemes: An Efficient Transmission Technique for Broadband Wireless Systems

Abstract

This paper considers frequency-domain re- ceiver design for OQPSK-type schemes. Since the I-Q interference can lead to significant performance degra- dation we propose an FDE design (Frequency-Domain Equalization) where there is no I-Q interference in the sampling instants for the predominant OQPSK constella- tion. We also propose iterative FDEs with I-Q interference cancelation, as well as the cancelation of unintended OQPSK components.
