Abstract

A method for dynamically scheduling multi-receive channel signal equalizer tasks, the method comprising: a computing device determining an estimated maximum Doppler frequency and an estimated delay spread of a wireless communication channel at a specific time; the computing device is based on The estimated maximum Doppler frequency and the estimated delay spread determine a task queue form and an update period of a predictive model order; the computing device selects a change in a predictive model order search range based on the determined task queue form rate; and the computing device generates a plurality of task control signals within a time period to control equalizer coefficients based on the task queue form, the update period of the predictive model order, and the search range of the predictive model order.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to dynamic task scheduling of a multi-receive channel equalizer. Background technique [0002] A specific mobile network may support a specific communication protocol that enables faster data transmission in the specific mobile network compared to other communication protocols. For example, compared with devices that support Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) technology, devices that support High-Speed ​​Downlink Packet Access (HSDPA, High-Speed ​​Downlink Packet Access) or Evolved High-Speed ​​Downlink Packet Access Technology (HSDPA+) mobile devices will have higher data speed and capacity. However, in order to achieve faster data transmission, such a device requires a relatively complex and expensive hardware structure. SUMMARY OF THE INVENTION [0003] In one aspect, the present invention provides a dyn...
