Ultra-high-speed Broadband 155mbps Wireless Access Communication System

The main content in this text is to confirm the overall scheme of the ultrafast broadband 155M wireless wired in communication system. Adopt QPSK system, develope the ultrafast intermediate frequency modem. Round the feature of the ultrafast speed, make the detailed description of phase noise, receiver noise figure, launch power, threshold level of system. In order to confirm the overall scheme, adopt QPSK system, expound the circuit design process and the performance analysis in detail.
