Abstract
Briefly, an adaptive transmitted power control scheme, which may be used in stations of a communication system, for example, a wireless communication system. The scheme may allocate transmission power to a communication station based on multiplying each of at least one transmitted subcarrier complex number by a corresponding subcarrier weight. Additionally, a detection scheme may detect whether a transmitted power control scheme according to an embodiment of the invention is used by stations of the communication system. The allocation of transmission power may be also used to transmit additional service information through channels.
