Abstract:
|
The well-known structure of an array combiner along with a maximum likelihood sequence estimator (MLSE) receiver
is the basis for the derivation of a space-time processor presenting
good properties in terms of co-channel and intersymbol interference
rejection. The use of spatial diversity at the receiver front-end
together with a scalar MLSE implies a joint design of the spatial
combiner and the impulse response for the sequence detector. This
is faced using the MMSE criterion under the constraint that the
desired user signal power is not cancelled, yielding an impulse response
for the sequence detector that is matched to the channel and
combiner response. The procedure maximizes the signal-to-noise
ratio at the input of the detector and exhibits excellent performance
in realistic multipath channels. |
