Patent ID: 7245879

Claim:
A method comprising: identifying at least a subset of a plurality of subcarrier(s) within a wireless channel that fail to meet a threshold channel performance metric; deactivating the identified subset of the plurality of subcarriers; and selectively distributing a power budget across a remaining subset of active subcarriers (N on ) to provide a substantially optimal channel throughput within the given power budget by determining a throughput for each of a plurality of combinations of modulation and encoding type (RATE(s)), identifying a maximal rate for a given set of channel characteristics and distributing the overall transmit power budget P total among the active subcarriers according to the following algorithm for generating a power coefficient for an i th subcarrier, P i = σ i 2 ∑ j = 1 N on opt ⁢ σ j 2 · P total , for i=1 . . . N on .
