Efficient signal detection for space-time block coding over time-selective fading channels
In this paper, we consider the signal detection for
space-time block coding over time-selective fading channels.
We derive a general maximum likelihood (ML) decision rule
for space-time block coding (STBC). The resulting detector is
valid for any number of receive antennas and for all STBC
systems that have the linear dispersion property. The detector
results in a quadratic minimization problem, which can be solved
efficiently by sphere decoding or nulling-and-cancelling detection.
For orthogonal STBC systems, we also propose a suboptimal
detector using the principle of parallel interference cancellation
(PIC) that is valid for systems with an arbitrary number of
receive antennas
