In this paper, two channel estimation schemes for OFDM systems are investigated in a time-variant channel. The orthogonality of the subcarriers is destroyed in a time-variant chann...
Abstract—This paper studies an efficient receiver design for concatenated space-frequency coded orthogonal frequency division multiplexing (OFDM) systems under severe multipath c...
—To establish the interference canceller, generating replicas of unwanted carriers is a key. This paper addresses the design and performances of two types of signal canceller tha...
