Báo Cáo An aptive turbo decoder for high-data rate applications

ABSTRACT
​

This paper presents the application of a turbo coding technique combined with a bandwidth
efficient method known as trellis coded modulation. A transformation applied to the incoming
I-channel and Q-channel symbols allows the use of an off-the-shelf B/QPSK turbo decoder
without any modifications. A conventional turbo decoder then operates on transformed symbols
to estimate the coded bits. The uncoded bits are decoded based on the estimated coded bits and
locations of the received symbols.
