Abstract:
1. A method for error reduction in a communication system comprising a plurality of communication devices and a plurality of orthogonal subcarriers, the method comprising steps of: determining, by a first communication device of the plurality of communication devices, an equalization function that reduces a multipath delay of a received signal; receiving, by a second communication device of the plurality of communication devices, subcarrier suppression information; suppressing, by the second communication device, an orthogonal subcarrier of the plurality of orthogonal subcarriers based on the received subcarrier suppression information to produce a suppressed subcarrier and a non-suppressed subcarrier; transmitting, by the second communication device, a signal comprising at least the non-suppressed subcarrier to produce a transmitted signal; receiving, by the first communication device, the transmitted signal to produce the received signal; and processing, by the first communication device, the received signal based on the determined equalization function.
