Patent ID: 7298696

Claim:
A blockage mitigation method for information transmission systems comprising: detecting channels, wherein the detecting channels comprises continuous counting of negative acknowledgements received at a transmitter during error detection and retransmission from a receiver; partitioning or segmenting the counting, wherein the partition or segmentation of the counting is arbitrary; monitoring the channels, wherein the monitoring channels comprises channel classification and identification, adapting blockage mitigation for the channels; wherein the adapting the blockage mitigation channels comprises selecting and switching the blockage mitigation; and constructing and deriving the blockage mitigation, wherein the construction and the derivation of the blockage mitigation measure, compare and evaluate systems performance criteria in terms of error probabilities and efficiencies for the systems comparison and evaluation, wherein the selecting and switching the blockage mitigation comprise measuring channel degradations due to blockage, wherein the measuring is performed in terms of total carrier power to noise density ratio.
