PROCEDE D'OPTIMISATION DE LA RECEPTION STEREO POUR RADIO ANALOGIQUE ET RECEPTEUR DE RADIO ANALOGIQUE ASSOCIE

摘要

A method of optimizing stereo reception for an analog radio by applying the demodulated right sound signal (SD) and left sound signal (SG) as input to a decorrelation module having a variable decorrelation rate. The decorrelation rate of the decorrelation module is modified as a function of the reception quality coefficient“alpha”provided by the radio. The decorrelation module applies a higher decorrelation rate for a smaller reception quality coefficient“alpha”and applies a lower decorrelation rate for a larger reception quality coefficient“alpha. Also, a module for generating high-pitched sounds to recreate the high-frequency component (SHF) of the right or left sound signals which has been removed in the event of poor reception.
