碩士 === 國立清華大學 === 電機工程學系 === 96 === For a conventional coded transmission scheme
operating in an inter-symbol interference (ISI) channel in which the
coded symbols are interleaved before being sent to the ISI channel,
the extrinsic information transfer (EXIT) curve of a
soft-in-soft-out (SISO) equalizer is steep for large equivalent
discrete channel length of an ISI channel. In this paper, we propose
to flatten the equalizer EXIT curve to match the close-to-horizontal
EXIT curves of the turbo decoder or convolutional decoder optimized
for AWGN channels by designing a transmission scheme which is
implemented by first interleaving a codeword with two adjacent
codewords and then transmitting the interleaved codewords
sequentially. Hence, the thresholds of proposed system are better
than those of the conventional system when the same channel codes
optimized for AWGN channels are used.
