摘要: A method and apparatus for allocating pilot carriers adaptively in an OFDMA communication system are disclosed. To improve phase error estimation performance optimize the number of allocated to each sub-channel, transmitter changes a sub-channel according status sub-channel. Consequently, less good state, reducing power consumption more bad improving channel despite increased consumption.
