Maximum-likelihood estimation of FIR channels excited by convolutionally encoded inputs.

Maximum-likelihood estimation of FIR channels excited by convolutionally encoded inputs.

If error correcting coding is present in the information symbols, the channel estimation procedure may be further complicated, since the encoder introduces a nonlinear operation on the information symbols (in the field of reals). Moreover, because of the encoder's memory, the input to the chann...
