ABSTRACT:
This invention relates to an equalizer for equalization of a linear modulated signal received in blocks or frames over a radio channel. The impulse response of the channel is estimated during training sequences before and after a frame and interpolation is used to estimate the impulse response at each point in the frame. From this, the coefficients of an equalizer (24, 26) are calculated for equalising the signal. Various further improvements are described. The technique is particularly applicable to land mobile radio systems using 16 QAM or other linear modulation schemes.
