Method and apparatus for communication in a multiple access network

摘要

A method of communicating by tracking time varying channels in a multiple access packet based communication network is described. The method comprises the steps of (a) initializing a channel estimate reference based on an initial channel estimate derived from a received packet preamble, (b) updating the channel estimate reference based on a packet data symbol channel estimate in a coded portion of the current and all previously received data symbols and (c) repeating step (b) at the arrival of subsequent packet data symbols.
