Apparatus and method for decoding turbo TCM using coset mapping |
摘要 |
A turbo TCM decoder for performing a soft decision without performing a sector phase quantization is disclosed. The turbo TCM decoder includes: a symbol transformer for converting a received signal to signal bits of QPSK mode by using an I-axis coordinate and a Q-axis coordinate on a constellation of the received signal; a phase sector quantizer for performing a phase sector quantization or the received signal by using the I-axis coordinate and the Q-axis coordinate; a first decoder for determining coded data by decoding the converted signal bits; a delay for delaying the quantized signal; and a second decoder for determining un-coded data by using the delayed quantized signal and the determined coded data.
