Patent ID: 7010029

Claim:
A method executed in a receiver that combines a decoder with an equalizer in a single module, comprising the steps of: said receiver receiving at time k a signal r(k); selecting as a signal transmitted by a transmitter a signal that minimizes the following equation metric ξ j ⁡ ( k ) =  r ⁡ ( k ) - ∑ l = L 1 + 1 L 1 ⁢ h _ j ⁡ ( l ) ⁢ s ~ ⁡ ( k - l ) - ∑ l = L 1 + 1 L + 1 ⁢ h ~ j ⁡ ( l ) ⁢ s ^ ⁡ ( k - l )  2 where {tilde over (h)} j (1) is related to both the transmission channel and to the encoding structure in said transmitter, {tilde over (s)}(k) is a trial symbol specified by a selected trellis transition and ŝ(k) is a symbol that was previously decided; and applying said selected signal to said decoder to decode received symbols.
