Understanding of transmission throughput and channel capacity in a systematic way

In this paper, our main focus is to find a proper way to understand the coherent relationship between reliable transmission throughput and channel capacity in a systematic way. To explicitly characterize the reliable throughput, we derive a new characterized quantity based on the Fano´s inequality, which combine source coding rate, or the selected transmission rate/modulation scheme and the error detection probability into an integrated form. We then extend it to continuous channels and obtain new measure for i.i.d block fading channels by considering QoS constraint and get some important insights that both high transmission efficiency and low outage probability can be achieved simultaneously only for either very high signal to noise ratio case or very low signal to noise ratio case. For the middle range of signal to noise ratio, both higher transmission efficiency and lower outage probability can not be achieved simultaneously.
