Patent Images
1. A method for determining transmit signal configuration parameters comprising:
- receiving a signal in a subscriber station;
determining, from the signal, a channel impulse response value between a base station and the subscriber station;
estimating channel characteristics based on the channel impulse response value;
determining transmit signal configuration parameters based on the estimated channel characteristics; and
selecting at least one of the configuration parameters based on an estimation of channel impulse response.

Abstract
A method and wireless system that is able to adapt forward channel signal parameters to the different channel characteristics in each deployment environment. For example, the base station may update the waveform parameters based upon the real-time channel measurement feedback as received from the subscriber stations.
