Abstract
A method for coherent estimation of the traffic-to-pilot energy ratio is presented. A received preamble is decoded, and then re-encoded. The received preamble is then multiplied by the re-encoded preamble. The results are summed, squared, and then divided by a pilot energy value. In another method, a message carrying energy information can be inserted between a subpacket preamble and a subpacket.
Claims7
A method for improving the performance of a decoder, comprising:
- determining an energy value for a transmission from a first station to a second station, the decoder residing in the second station;
- forming a message carrying the energy value;
- and
- transmitting the message to the second station.
