Finite impulse response filtering for an adaptive modulation wireless communication system

Finite impulse response filtering for an adaptive modulation wireless communication system

The present invention relates to a method of updating the weights of a FIR filter where the filter processes symbols having variable modulation rates. When the modulation rate of the incoming symbols changes, the weights corresponding to the first symbol having the new modulation rate are changed ba...

Zusammenfassung:The present invention relates to a method of updating the weights of a FIR filter where the filter processes symbols having variable modulation rates. When the modulation rate of the incoming symbols changes, the weights corresponding to the first symbol having the new modulation rate are changed based as the symbol propagates through the filter.
