Joint transmitter and receiver design for MIMO channel shortening
conference contribution
posted on 2009-12-14, 12:22 authored by Cenk Toker, Sangarapillai LambotharanSangarapillai Lambotharan, Jonathon ChambersThe problem of joint transmitter and receiver design for
multi-input multi-output (MIMO) channel shortening for frequency-
selective fading channel is addressed. A frequency
domain approach is followed which is equivalent to infinite
length time-domain channel shortening equalizers (TEQ).
A practical joint space and frequency waterfilling algorithm
is also provided for optimum transmit power loading. It is
demonstrated that the finite length TEQ suffers from a flooring
effect on the compression ratio performance, whereas
the proposed method overcomes this disadvantage. The noise
amplification and the compression performance of the proposed
joint tranceiver method is found to be better than both
finite and infinite length receiver-only designs, with a gain
of order of 3dB for a 2x2 MIMO channel.
