lte上行链路，生成发送端的pucch信道信息，包括符号以及导频序列，pucch格式为1b，开发环境为ccs3.3-lte uplink, the sender s pucch channel and pilot symbol sequence generation, format 1b

基于hdl的ofdm基带处理器发射机的设计与实现 包括 工作时钟 主控单元 导频插入 长短训练序列生成 data符号调制 循环前缀与加窗处理 IFFT/FFT 信道编码 扰码模块等-Hdl of ofdm transmitter baseband processor based design and implementation including work clock master unit pilot insertion length of the training sequence g

symbols, because covering all frequencies, could be effective against the selective frequency fading, but more sensitive for the impact of fast fading channel. Therefore, the block-type pilot is developed under the assumption of slow fading channel.
