A new blind rate decision algorithm
Jaehong Kim, Jun-Jin Kong · 2002
In variable rate communication systems where the information of the data rate is not given to the receiver, estimating the data rate in the receiver is a very important factor in terms of determining the receiver performance. So far many algorithms estimating the received data rate have been proposed. The most popular one is the post-rate decision method using the Viterbi decoder. It causes the large power consumption due to high complexity, and requires much processing time. A new pre-rate decision method using a pre-decoder is proposed, which has a relatively simple structure in comparison with the Viterbi decoder. Compared with other existing algorithms, the proposed algorithm reduces the power consumption and increases the processing speed in the systems.
