Abstract

A method a system for automatically controlling an adaptive interleaver involves monitoring performance parameters of a transmission system and controlling the adaptive interleaver in response to the performance parameters. The SNR and the data rate of the transmission system are preferably determined. The data rate is analyzed and the adaptive interleaver is adjusted in response to the data rate and the SNR. Alternatively, the BER and the data rate of the transmission system are determined. The data rate is analyzed and the adaptive interleaver is adjusted in response to the data rate and the BER. Alternatively, any one of the SNR, BER or data rate can alone be monitored and used to the adaptive interleaver. The system provides a effective system for adjusting an adaptive interleaver in response to performance parameters of a transmission system.

Claims (23)

1. A hardware implemented method in a controller for an adaptive interleaver comprising steps to:

determine the signal to noise ratio of the transmission channel;

determine the data rate of the transmission channel;

determine whether the data rate exceeds a threshold;

analyze the signal to noise ratio of a transmission channel;

analyze the data rate of the transmission channel; and

generate a interleave control signal based on the analysis of the signal to noise ratio and the data rate of the transmission channel wherein the signal controls an interleave depth.

2. The hardware implemented method of claim 1 , wherein the control signal is an analog signal.

3. The hardware implemented method of claim 1 , wherein the control signal is a digital signal.

4. A computer implemented method implemented for controlling an adaptive interleaver comprising steps of:

determining the signal to noise ratio of the transmission channel;

determining the data rate of the transmission channel;

determining whether the data rate exceeds a threshold;

analyzing the signal to noise ratio of a transmission channel;

analyzing the data rate of the transmission channel; and

generating a interleave control signal based on the analysis of the signal to noise ratio and the data rate of the transmission channel wherein the signal controls an interleave depth.
