Patent number: 9148319Abstract: Dynamically scheduling multi-receive-path signal equalizer tasks. An estimated maximum Doppler frequency and an estimated delay spread of a particular wireless communications channel may be determined at a particular time. A particular task queue format and a particular predictor model order update period may be identified based on the estimated maximum Doppler frequency and delay spread. A particular predictor model order update rate may be selected based on the identified particular equalizer task queue format. A plurality of task control signals may be generated based on the particular task queue format, the particular predictor model order-update period, and the particular predictor model order-search range, to control equalizer coefficient generation within a particular time period.Type: GrantFiled: February 20, 2013Date of Patent: September 29, 2015Assignee: SHANGHAI MOBILEPEAK SEMICONDUCTOR CO., LTD.Inventors: Feng Wan, Weiping Xu, Yuan Li, Qiuzhen Zou
