Abstract :
This paper examines the average error performance of a three-phase digital network coding scheme that employs single antenna selection for orthogonal frequency-division multiplexed signal transmission in frequency-selective Rayleigh fading channels. The average error performance of the scheme with a single-antenna relay is observed for convolutional-coded M-ary symbols in the presence of channel estimation errors. An improved antenna selection criterion providing enhanced performance gains is proposed and demonstrated.
