... order to identify the potentially most reliable channel quality measure to be used in our BbB adaptive turbo-coded QAM modems to be designed during our forthcoming discourse, we will now analyse ... over the range of 0 to 5 for BPSK and 4-QAM, 0 to 6 for 16-QAM and 0 to 10 for 64-QAM. Thus, there is no average LLR magnitude improvement upon introducing turbo decoding in this l...

... BEP PaUg of our adaptive modulation scheme 6.3. SYSTEM DESCRIPTION 201 can be represented as the sum of the BEPs of the specific constituent modes divided by the average adaptive modem throughput ... mode-specific average BEP given in (6.20) and B is the average adaptive modem throughput given in (6.15) or in (6.18). The aim of our adaptive system is to transmit as high a...
