Title: Method for initially setting communication system having receiver and transmitter of different bandwidth
Inventor: MUJICA FERNANDO A
IPC: H04J1/00
Filed: 2002-06-11
Abstract: PROBLEM TO BE SOLVED: To evaluate the influence of aliasing spectrum during the initial setting sequence of a communication system, and at the same time to compensate for it. SOLUTION: A receiver for a reduced channel bandwidth receives information that has a known bandwidth B and a known spectrum 20. The received information preferably has a multicarrier modulating signal, for example, the form of a DMT signal. The aliasing spectrum 24 is calculated based on the know spectrum 20 and at the same time the difference in frequency between the known bandwidth B and the reduced channel bandwidth. Then, the received information is corrected based on an aliasing function to compensate for alias strain. For example, the received information can be corrected by correcting the noise component of the received information or the signal to noise ratio.
