Title: Phase shift keying receiver and correction method of imbalance in amplitude and phase
Inventor: OZLUTURK FATIH M
IPC: H03C3/02
Filed: 2007-07-19
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a bit error rate of a received QPSK signal by balancing an amplitude and a phase of the signal when it is received.  <P>SOLUTION: The amplitude and the phase of the received QPSK signal that may have been corrupted during transmission are balanced. The system determines the amplitude of the I and Q symbols of a received signal, compares their values, and applies correction to one or other channels to correct amplitude imbalance. In order to adjust phase imbalance, the system calculates the cross-correlation between the I and Q symbols which should be averaged to zero. Correction factors are extracted from the cross-correlation and added to both channels to zero the phase cross-correlation. An output from the system is a signal containing both the amplitude and the phase with the correction applied.  <P>COPYRIGHT: (C)2008,JPO&INPIT
