Abstract

A method for coherent estimation of the traffic-to-pilot energy ratio is presented. A received preamble is decoded (20), and then re-encoded (22). The received preamble is then multiplied by the re-encoded preamble (23). The results are summmed (24), squared (26), and then divided by a pilot energy value (28). In another method, a message (41) carrying energy information can be inserted between a subpacket preamble (40) and a subpacket (42).
