Abstract [en]

In communication applications it is important for

equalization to have a good estimate of the channel over which

the signal was transfered.

In this paper we introduce the concept of

model averaging, where several channel estimates are used in a weighted

manner, to sparse communication channel estimation and equalization for

channels with intersymbol interference.

We show via numerical

examples that the bit-error-rate (BER) can be reduced by

our suggested method, compared to the BERs obtained using

channel estimation methods not assuming any sparsity of the channel.
