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.
Claims30
A method comprising:
- decoding first preamble symbols received at a base station to generate decoded first preamble symbols;
- encoding the decoded first preamble symbols to generate second preamble symbols;
- determining an energy value associated with a transmission between the base station and a remote station, wherein the energy value is determined based at least in part on a sequence of symbols generated by a multiplication of the first preamble symbols and the second preamble symbols;
- forming a message including an indicator associated with the energy value;
- and
- transmitting the message in a channel to the remote station.
