Claim:
1. A data detection method, comprising the steps of: a. receiving a signal transmitted over a communication channel, said signal being representative of at least a stream of interfering symbols x b. filtering the received signal through at least a filter bank comprising at least a first filter representative of a linear response of said channel and a second filter representative of a non-linear response of said channel, and sampling the filtered signals at the symbol rate, thus obtaining respective sequences of filtered samples r c. jointly computing the a posteriori probabilities of N>1 consecutive symbols x where: thus realizing simultaneous soft-input-soft-output detection of a packet of N symbols of the transmitted message, and wherein said probability mass function is expressed by: where: x is a vector constituted by N symbols x σ is a vector formed by N trellis states σ r is a vector constituted by said sequences of filtered samples; I P(x wherein for F k (x k ,σ k ) and H i (x k , x k−i ) ; and and wherein the functions γ 1 h (1) (t) and ¾ 3 γ 3 h (3) (t 1 , t 2 , t 3 ) are Volterra kernels of first and third order, respectively.
