摘要: The present invention relates to a carrier recovery device for Costas loop comprising voltage-controlled oscillator (12) and two branch filters (14, 15) connected this by way of filter (12), in which the have different characteristics, (17) is across paths: - direct path (18) parallel (19) an amplifier (20) series with (21). Application particular space transmissions.
