This paper addresses the correction of multiple carrier frequency offsets (CFO) and detection in vertical Bell Labs layered space-time (V-BLAST) orthogonal frequency division multiplexing (OFDM) systems with distributed transmit antennas. We first propose a low-complexity CFO correction method suitable for low delay spread channels by exploiting the underlying characteristics of zero-forcing (ZF)...
This correspondence focuses on the correction of carrier frequency offsets (CFOs) in orthogonal frequency-division multiplexing (OFDM)-based spatial multiplexing multi-input-multi-output (MIMO) with distributed transmit antennas, where the CFOs between the receiver and each transmit antenna are possibly different. Considering macroscopic fading and multipath Rayleigh fading, the average power of the...
