1. 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 (Non) 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 Ptotal among the active subcarriers according to the following algorithm for generating a power coefficient for an ith subcarrier, for i=1 . . . Non.
