A connection structure for a composite backrest and a method for making the same are provided. The connection structure includes two frames, a backrest body, and metal bushings. The metal bushings include a group of left metal bushings and a group of right metal bushings. The two frames are respectively fixed to the left side and the right side of the backrest body by the left metal bushings and the right metal bushings. The method includes: punching the backrest body and the frames; placing the frames into the backrest body; processing the metal bushings; sandblasting or sanding the external surface of the metal bushing; coating a configured structural adhesive on the metal bushing, and oppositely bonding the metal bushing; fixing the bonded metal bushing by a tool; and placing the fixed metal bushing, the composite backrest and the two frames into a drying oven for heating.

The present disclosure provides a non-linear receiver, an asymmetric decision feedback equalization circuit and method, including: converting an optical signal emitted by a laser device into an electrical signal; obtaining a compensation amplitude of a current data in the electrical signal by obtaining an actual amplitude of the current data, and compensating the current data based on a logic value of k prior data of the current data and a feedback coefficient corresponding to the prior data; comparing the compensation amplitude of the current data with a decision threshold to determine the logic value of the current data; the feedback coefficient is an absolute value of an influence amount of the prior data on an amplitude of the current data, and k is a positive integer. The present disclosure can overcome the bit error problem of the receiver and reduce jitter of the clock recovered by the clock recovery circuit.
