摘要：
A process for performing a QR Decomposition of a channel matrix of a wireless communication channel system, said process involving the steps of: performing a full QR Decomposition of one channel matrix for the purpose of deriving a first QR representation of the channel; performing a second iterative QR Decomposition of an adjacent channel matrix, said second iterative QR Decomposition using the results of said first QR representation as well as the difference of the two adjacent channel matrices ΔH. More particularly, the process is characterized in that the iterative QR Decomposition is performed in response to the detection of a high level of workload of the processor.
