From: Reduced complexity Log-MAP algorithm with Jensen inequality based non-recursive max∗ operator for turbo TCM decoding

Algorithm	Overall number	Reduction wrt
	of operations	Log-MAP
Log-MAP	1,154	—
AvN Log-MAP	794	31.2%
Linear Log-MAP	1,154	0%
Average Log-MAP	983	14.8%
Shift Log-MAP	1,126	2.5%
Max-Log-MAP	554	52%
