Abstract

In a receiver, a plurality of amplifiers each having a particular amplification factor amplifies a received signal. Analog-to-digital converters (ADCs) each converts the output of the respective amplifier to a digital value. The resulting digital values from the ADCs are written to respective memories. At the same time, maximum amplitude detectors respectively detect the maximum amplitudes of the associated digital values. A comparator locates, among the lines where the maximum amplitude of a burst does not reach either a positive saturation level or a negative saturation level, the line having a great amplification factor every time a burst appears. On receiving a control signal from the comparator, a selector transfers the digital value stored in the memory of the line selected to a signal processor. The signal processor demodulates and decodes the received signal based on the input digital value and delivers the output thereof to an output terminal.
