The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for the coding (compression) of natural video images. The new standard [1] will be known as H.264 and also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding: Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC). This document provides a short introduction to CABAC. Familiarity with the concept of Arithmetic Coding is assumed.

Testbenches have become an integral part of the design process, enabling you to verify that your HDL model is sufficiently tested before implementing your design and helping you automate the design verification process. It is essential, therefore, that you have confidence your testbench is thoroughly exercising your design. Collecting code coverage statistics during simulation helps to ensure the quality and thoroughness of your tests.

函数名称:CRC-16 Process 函数原型:INT16U make_crc16(INT8U *msgaddr,INT8U datalen) 函数功能:进行CRC校验和产生CRC代码.这个函数只影响全局变量crc16. 校验字放在字符串最后,低8位在前高8位在后. msgaddr : 进行CRC16校验的据块的首地址 datalen : 进行CRC16校验的据块的个数 CRC-ITU的计算算法如下: a.寄存器组初始化为全"1"(0xFFFF)。 b.寄存器组向右移动一个字节。 c.刚移出的那个字节与数据字节进行异或运算,得出一个指向值表的索引。 d.索引所指的表值与寄存器组做异或运算。 f.数据指针加1,如果数据没有全部处理完,则重复步骤b。 g.寄存器组取反,得到CRC,附加在数据之后(这一步可省略)。

In recent years large scientific interest has been devoted to joint data decoding and parameter estimation techniques. In this paper, iterative turbo decoding joint to channel frequency and phase estimation is proposed. The phase and frequency estimator is embedded into the structure of the turbo decoder itself, taking into consideration both turbo interleaving and puncturing. Results show that the proposed technique outperforms conventional approaches both in terms of detection capabilities and implementation complexity.

This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm is based on the interpolation technique for two correlation values in the frequency and phase domains. This simple interpolation technique can significantly improve frequency and phase resolution capabilities of the proposed technique without increasing the number of the correlation values. In addition, the overall block diagram of a digital communications receiver for DVB-RCS is presented, which was designed using the proposed estimation algorithms. Index Terms—Carrier phase estimation, DVB-RCS, frequency offset estimation, interpolation, joint estimation, MF-TDMA.
