Parameter adaptive adjustment method, device and electronic equipment

Abstract

The invention provides an adaptive parameter adjustment method and device and electronic equipment. The method is used for adjusting configuration parameters of a continuous time linear equalizer (CTLE) and decision feedback equalizer (DFE) which are cascaded on the input side of a pseudo-random binary sequence (PRBS) decoding module according to decoding data output by the PRBS decoding module. The method comprises the following steps: determining a plurality of PRBS code error values on the basis of a plurality of pieces of decoding data and preset coding data; if first mean values and firstvariances of the PRBS code error values do not meet a first preset condition, adjusting a compensation value of the CTLE until the PRBS code error value determined on the basis of the decoding data output by the PRBS decoding module after the compensation value of the CTLE is adjusted is minimum; and adjusting tap coefficients of the DFE one by one until the PRBS code error value determined on the basis of the decoding data output by the PRBS decoding module after the tap coefficients of the DFE are adjusted is zero. Software and hardware can work cooperatively, and the technical effects of automatic completion and higher efficiency can be achieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a parameter self-adaptive adjustment method, device and electronic equipment. Background technique [0002] In the communication process of long-distance high-speed serial data transmission system (rate of 6.25G and above), the baseband signal is often affected by various noise interference due to the need for long-distance and high-speed transmission, the most common of which is the signal code interfering. In addition, the signal bandwidth is limited, and the high-frequency part of the signal is severely weakened. In the end, the transmission signal cannot obtain an effective signal due to serious attenuation and distortion problems. The most effective technology in removing interference, correcting and compensating signals is the receiver equalization technology. For long-distance high-speed transmission, it is necessary to use the equalization technology com...
