Abstract :
This paper introduces order-recursive QRD-based least-squares lattice (QRD-LSL) smoothers for adaptive equalization. The QRD-LSL smoothers use past, present and future received data sequences to estimate the present value of the transmitted data sequence. Except for an overall delay needed for physical realization, QRD-LSL smoothers can substantially outperform conventional QRD-LSL filters in adaptive equalization while retaining all the advantages of an order-recursive structure
