METHOD AND SYSTEM FOR CALCULATING CHANNEL GAIN

The system determines at least one property of a communication channel which connects a transmitter and a receiver. The system includes a device (134) for generating values of at least sampled sections of a received signal which is received by the receiver after transmission over the channel. The va...

Summary:The system determines at least one property of a communication channel which connects a transmitter and a receiver. The system includes a device (134) for generating values of at least sampled sections of a received signal which is received by the receiver after transmission over the channel. The variance of the generated values is then determined (146). Another device (154) quantises the values of the received signal to provide a quantised value. An error signal is then provided (162) in response to the difference between the values of the sample, received signal and the quantised values. A device (170) calculates the variance of the error signal. The channel amplification property of the communication channel is then calculated (178) in response to the variance of the generated values and the error signal.
