摘要

WiMAX 規格802.16-2004共有五個實體層，其中正交分頻多工(orthogonal frequency division multiplexing,OFDM)實體層包含了三種錯誤更正碼，本論文選擇里德索羅門(Reed Solomon, RS)碼與迴旋碼(convolutional code, CC)的串接碼:RS-CC錯誤更正碼為討論的對象。本文說明了RS-CC錯誤更正碼的編解碼原理，並附加例子輔助說明，同時依編解碼順序提供傳送端、接收端各功能區塊演算法。

The standard 802.16-2004 for WiMAX contains five physical layers, in which OFDM physical layer comprises three kinds of error correcting codes. In this paper the concatenated code for Reed-Solomon code and convolutional code is considered as a subject for discussion. This paper illustrates encoding/decoding principle for RS-CC with some examples, and introduces encoding/decoding algorithms for the transmitter and receiver in order.
