Abstract:
The present invention is concerned with Cosine Modulated Filter Band modulation, in particular for a matrix equalizer for equalising a modulated signal carrying digital data, wherein the signal is modulated using a CMF6 and transmitted through a transmission channel having a channel impulse response c(t), wherein the matrix equalizer comprises: matrix coefficients W(i) determined based on the discrete-time matrix channel impulse response C(i) that is determined from the channel impulse response c(t); wherein the matrix equalizer is configured to equalize the modulated signal in order to reduce signal distortion introduced by the transmission channel. The present invention also concerns a method for equalising the CMFB modulated signal.

Claim (Index 10):
A matrix equalizer at a receiver for equalising a modulated signal carrying digital data, wherein the signal is modulated using a Cosine Modulated Filter Bank CMFB at a sender and transmitted through a transmission channel having a channel impulse response c(t), wherein the matrix equalizer is configured to:\n determine the matrix channel impulse response c(t) in the time domain, map the channel impulse response c(t) to a discrete-time matrix channel impulse response C(i), in order to obtain the discrete-time matrix channel impulse response C(i), determine matrix coefficients W(i) based on a linear system of equations using the discrete-time matrix channel impulse response C(i) and statistical parameters of the digital signal, and equalize the modulated signal using the matrix coefficients W(i) in order to reduce signal distortion introduced by the transmission channel.
