摘要：
A new concept of Bit Geometrical Uniformity (BGU) is introduced to help the analysis and estimation of performance of systems with Iterative Detection/Decoding (ID). It is also shown that the BGU labelings of the signal constellation allows a fast search for best component binary Recursive Systematic Convolutional (RSC) codes of a BICM-ID system using both of overall and in-line interleaving. Best rate-1/2 RSC codes are reported for 4PSK constellation as an example. The new concept and new search method can be directly extended to MPSK and MQAM constellations.
