MUD in MIMO channel

Started by Nghi Le Dinh June 21, 2007
Dear all

I have a question about MIMO

In Multiuser Detection in MIMO (or MIMO-OFDM) systems using MMSE, when using
number of transmit antennas is equal number of receive antennas or number of
transmit antennas is fewer number of receive antennas, which give the better
results? Why?

Hope to have your helpings.

Thanks
1. Ntx and Nrx (=Ntx)

2. Ntx and Nrx ( > Nrx)

Theoretically the other alternative of having more rx antenna will give
better performance. This is because now receiver has more information so
the signal processing should be yielding better results compare to first
alternative.

Thanks and Regards,

Amit Shaw
