摘要
A method of mitigating power consumption in a DVB-H receiver is provided. The method may include predicting reception error(s) associated with a data burst to be received by the receiver, and deciding, based on the prediction result, to process or to eschew processing of MPE-FEC redundancy section(s) associated with the data burst, prior to the reception of the data burst. Predicting may include evaluating reception quality before receiving the data burst, by using data provided by the receiver's demodulator, wherein evaluating may be based on calculating a reception function (F) at the receiver, by using measured or calculated, scaled or weighted, parameter(s) associated with data received prior to the reception of the data burst. MPE-FEC redundancy section(s) associated with a received data burst may be processed only if the value of the reception function F is greater than a predetermined threshold value. Predicting may be based on data provided by the receiver's MPE-FEC unit. The scaling/weighting factors may be adjusted according to a policy to optimize reception conditions. Prediction may be enhanced by considering reception history, by utilizing reception function. A receiver is also provided, which utilizes the method.
