Mixed direct-indirect adaptation procedure applied to receiver filter

An direct adaptation receiver for providing an estimated payload data sequence ({circumflex over (b)}), said receiver comprising:

• an apparatus for generating a regenerated data sequence free of said control sequence comprising:
• a channel identification unit receiving, from a communication channel, a transmitted signal ({tilde over (r)}) and a training control sequence (ptrain) to provide a plurality of channel coefficients representative of said communication channel (ĥ1 . . . ĥk);
• and
• a channel modeling unit filtering said plurality of channel coefficients representative of said communication channel (ĥ1 . . . ĥk) with said training control sequence (ptrain) to provide regenerated control sequence (rpilot);
• a control signal cancellation unit, subtracting said regenerated control sequence (rpilot) from said transmitted signal ({tilde over (r)}) to provide said control sequence free ({tilde over (r)}pilot free) of said control sequence;
• and
• a filtering unit receiving said regenerated data sequence free of said control sequence and further selectively receiving a training data sequence (btrain) to provide said estimated payload data sequence ({circumflex over (b)});
• and
• wherein said filtering unit is adapted in accordance with said training data sequence (btrain).
