【摘要】 DVB-H标准全称为手持数字视频广播(Digital Video BroadcastingHandheld)，是DVB组织通过地面数字广播网络向便携／手持终端提供多媒体业务所制定的标准：DVB-H标准被认为是DVB-T标准的扩展应用。但是和DVB-T相比，DVB-H终端具有更低的功耗，移动接受和抗干扰性能更为优越，因此该标准适用于移动电话，手持计算机等小型便携设备通过地面数字电视广播网络接收数字电视信号。本文对DVB-H发射端和接收端的部分信道处理算法和其实现做了重点研究。首先在DVB-T的基础之上对DVB-H发射端系统的SOPC实现做了探索，从SOPC设计方法学的角度设计了外码部分的加扰，RS编码，字节交织和内码部分的卷积删余编码，比特交织，符号交织这些模块。接下来对DVB-H接收芯片中的RS译码的算法和实现做了充分研究。本文在RS译码的设计当中，在并行Berlekamp-Massey(BM)算法基础上，采用了串行无逆Berlekamp-Massey算法和3级流水线的处理结构。采用此方法不仅避免了求逆运算，而且只需3个有限域乘法器就可以实现，大大降低了硬件的资源开销。更多还原

【Abstract】 DVB-H(Digital Video Broadcasting Handheld) is an ETSI standard for bringing services to handheld receivers, which is considered as the extended use of DVB-T standard. Compared to DVB-T, DVB-H terminal has lower power consumption and more excellent performance in mobile reception and interference tolerance , thus, which is more suitable for mobile phone, handheld receivers to receive digital TV signal through terrestrial digital broadcasting network.The thesis focuses on the partly channel processing algorithm and its implementation in the DVB-H’s transmitter and receiver.Firstly, the thesis discuss the SOPC implementation of DVB-H transmitter. It present the design of Scramble, RS encoder, Byte interleaver, convolution puncturing encoder, bit interleave, symbol interleave from the point of SOPC design.Following, the thesis presents the detailed description of RS decoder algorithm and its implementation. In the design of RS decoder, The inversionless Berlekamp-Massey(BM)algorithm with serial mode is used, which avoids the inversion computation and need only 3 finite-field multipliers. Thus, the consumption of hardware resources is mostly reduced. A 3-level pipe-line processing architecture is also used in the implementation of RS decoder.更多还原
