Combined Spatial and Temporal Equalization for Mobile
Proceedings of Nordic Radio Symposium,
Linköping, Sweden, October 26-27, 1994, pp 7-10.
A motivation for the method presented in this paper is
the expansion of mobile radio
communications. Here data are transmitted in bursts,
where attached to each burst is a training sequence of short duration.
The purpose is to investigate what can be gained by
combining spatial and temporal equalization in particular for
short training sequences. The
motivation for combining spatial and temporal equalization
is the existence of multipath
propagation and co-channel interference. Our main concern
is to obtain good performance yet low complexity.
We will suggest a low complexity algorithm utilizing a circular
antenna array. Although it has inferior performance in an
asymptotic sense, it turns out to be superior to the
general solution for short training sequences.
This conclusion is supported by simulations where
a number of algorithms are evaluated for different
scenarios involving co-channel interference.
The suggested algorithm can also be extended to multi-user detection.
