Abstract
We investigate limitations of the minimum mean square error (MMSE) solution for subband adaptive equalisers due to aliasing and error in power complementarity. By deriving the Wiener solution for the subband equaliser and comparing it against simulations, we verify that aliasing caused in the subband decimation can be considered equivalent to channel noise. We discuss how these limitations can be mitigated by careful system design.
