In this paper, we propose a new construction of linear unitary precoders
for multiple antenna fading channels based on an information theoretical tool
and we compare its performance with some known algebraic precoders.
The new precoder has been selected in the ensemble of random
unitary precoders by minimizing the outage probability associated to the
instantaneous mutual information. Then we consider a bit-interleaved coded modulation
where a non-systematic non-recursive convolutional code is cascaded
with a linear modulation and a block-fading multiple antenna channel.
The word error rate performance of the proposed precoder is illustrated under
iterative detection and decoding.
