1. Direct-conversion receiver for a communication system using modulation with non-constant envelope, comprising an analog stage for receiving an incident signal of a transmission channel and comprising transposition means (Mx) and programmable-gain amplification means (PGA), characterized in that it furthermore comprises at least one compensation module (MDM, STR) possessing an input terminal (BE) and an output terminal (STR) which are connected between the output of the transposition means (Mx) and the input of the amplification means (PGA), and which is able to compensate both for a static DC voltage offset and a possible dynamic DC voltage offset of the analog stage.
