RATE ADAPTATION METHOD USING BIT ERROR RATE FOR MULTIMEDIA SERVICE AND APPARATUS THEREFOR

摘要

Rate adaptation is carried out using bit error rate (BER) to enable effective multimedia transmission. The BER can be estimated using signal strength in a MAC layer and modulation information (FIGS. 7-9), and can be compatibly used in different wireless networks by means of message standardization.
