Study the Performance of Mobile Wimax Convolutional Turbo Code
نویسنده
چکیده
A useful tool in the design of reliable digital communication systems is channel coding. Turbo codes have been shown to yield an outstanding coding gain close to theoretical Shannon limit in the Additive White Gaussian Noise (AWGN) channel. This is due to relatively large coding gains that can be achieved. Over the past decade, turbo codes have been widely considered to be one of the most powerful error control code of a practical importance. This paper introduces the topic of WiMAX turbo coding. First, it gives an overview about the WiMAX Standards, then the WiMAX convolutional turbo code is introduced and its bit error rate performance is evaluated, by simulation, for different transmission conditions. keywords WiMAX, OFDM, OFDMA, Turbo codes, Log-MAP, Max-Log-Map.
