Log-Map / Max-Log-Map译码器的设计

Design of Log-Map / Max-Log-Map Decoder

Mihai Timis

摘要:

Turbo码解码的过程开始于为每个数据比特形成后验概率(APP),随后选择与该数据比特的最大后验(MAP)概率相对应的数据比特值。在接收到被破坏的码位序列时,利用APP进行的决策过程允许MAP算法确定在每个位时间最有可能已被发送的信息位。

英文摘要:

The process of turbo-code decoding starts with the formation of a posteriori probabilities (APPs) for each data bit, which is followed by choosing the data-bit value that corresponds to the maximum a posteriori (MAP) probability for that data bit. Upon reception of a corrupted code-bit sequence, the process of decision making with APPs allows the MAP algorithm to determine the most likely information bit to have been transmitted at each bit time.
