[3G develop] turbo_sys_demo DL : 0: This script simulates the classical turbo encoding-decoding system. It simulates parallel concatenated convolutional codes. Two component rate 1/2 RSC (Recursive Systematic Convolutional) component encoders are assumed. First encoder is terminated with tails bits. (Info + tail) bits are scrambled and passed to the second encoder, while second encoder is left open without tail bits of itself. Random information bits are modulated into +1/-1, and transmitted through a AWGN channel. Interleavers are randomly generated for each frame. Log-MAP algorithm without quantization or approximation is used. By making use of ln(e^x+e^y) = max(x,y) + ln(1+e^(-abs(x-y))), the Log-MAP can be simplified with a look-up table for the correction function. If use approximation ln(e^x+e^y) = max(x,y), it becomes MAX-Log-MAP.- This script simulates the classical turbo encoding-decoding system. It simulates parallel concatenated convolutional codes.

This paper introduces the standard from two aspects of system level and physical layer, gives the system structure diagram of sender and receiver, focuses on the characteristics of physical layer in the standard, and summarizes the important characteristics and key technologies of the standard. Secondly, two kinds of encoders are studied and implemented. According to the characteristics of the standard code matrix, an efficient encoder is designed and implemented. On this basis, a new encoding structure, rotary code, is proposed. The structure of rotary encoder is explored, and its simulation and implementation are completed.)
