titleOfInvention |
Method and apparatus for reducing amplitude variation and interference in a communication signal, such as in a wireless communication signal using inserted pilot symbols |
abstract |
The invention provides a method and apparatus for reducing transmission signal power or interference of transmitted communication signals suitable for use in a communication system having a base station and a plurality of user stations that exchange communication signals with the base station. An input node receives channel data for transmission on a plurality of channels to the plurality of user stations, wherein the channel data includes pilot symbol data. A processor determines symbol positions in which each of the plurality of user stations expect to find pilot symbols. A transmitter transmits to the plurality of user stations pilot symbols only in symbol positions that the plurality of user stations expect to find pilot symbols, and failing to transmit pilot symbols in other symbol positions. |
