直接数字频率综合器，采用ROM压缩法，经过FPGA验证和AISC实现-Direct digital frequency synthesizer, using ROM compression method, validation and AISC through FPGA Implementation

LTE system, OFDM modulation and Turbo Coding, including Viterbi, BCJR and SOVA are extensively analysed, ending up with a system performance specification. These are used to implement a fixed length Turbo encoder, a 16-QAM modulator a
