Abstract
A receiver comprises input means for receiving a signal (r(t)) of a first domain. Processor means are provided for applying a transform function to the received signal to a second domain. A first extractor arrangement extracts first type of information from the signal in the second domain. A plurality of processor means, each of which is arranged to receive a plurality of information portions, apply said transform function thereto and provide a transformed output. A second extractor arrangement extracts a second, different type of information from the output of each said plurality of processor means. Compensation Circuitry compensates the received signal using one of the second type of information extracted.
Claims20
A receiver comprising:
- means for receiving a signal of a first domain;
- means for applying a transform function to the received signal to transform the signal to a second domain;
- a first extractor arrangement for extracting a first type of information from the signal in the second domain;
- a plurality of means for processing, each of which is arranged to receive a plurality of information portions, apply a transform function thereto and provide a transformed output at each of the plurality of means for processing;
- a second extractor arrangement for extracting a second, different type of information from an output of each of the plurality of means for processing;
- and
- circuitry for compensating the received signal using one of the second type of information extracted from one of the outputs of the plurality of means for processing.
A receiving method comprising:
- receiving a signal in a first domain:
- applying a transform function to the received signal to transform the signal to a second domain;
- extracting a first type of information from the signal in the second domain;
- applying the transform function to a plurality of different information portions;
- extracting a second different type of information from each of the plurality of different information portions to which the transform function has been applied;
- and
- compensating the received signal using the second type of information.
