After introduction of the whole fpga design of uwb link , chapter four schemed out every function module such as frame structure , spread spectrum and modulation etc . lots of structure schemes and simulation waves were presented . chapter five expatiated the design scheme of uwb receiver , including mainly pulse synchronization , frame synchronization , demodulation and deframe 第五章在tr _ uwb系統(tǒng)的基礎(chǔ)上,詳細介紹了uwb收發(fā)信機的設(shè)計實現(xiàn)方法,然后重點對收發(fā)信機中的每個模塊進行設(shè)計,給出了各個模塊的具體設(shè)計框圖以及功能仿真結(jié)果,驗證了各模塊的正確性。
