摘要 |
A method of characterising a radio frequency traffic channel comprising a transmitter and a receiver is disclosed. The method comprises:
(a) sending a sequence of bits from the transmitter to the receiver at a first amplitude;(b) measuring which of said bits are accurately received by the receiver;(c) calculating an error rate of the radio frequency traffic channel based on the bits received;(d) using the calculated error rate to calculate a second amplitude which differs from the first amplitude by a first difference;(e) sending a further sequence of bits from the transmitter at said second amplitude and measuring which are accurately received in order to calculate a new error rate;(f) comparing the new error rate to a target error rate in order to determine whether the new error rate differs from the target error rate by more than a predetermined amount; and(g) if the new error rate differs from the target error rate by more than the predetermined amount, calculating a third amplitude, which differs from the first amplitude by a second difference which is smaller than the first difference; or(h) if the new error rate differs from the target error rate by less than the predetermined amount, calculating a third amplitude which differs from the second amplitude by a second difference which is calculated using the new error rate. |
