E1 Spread Spectrum Radios 1 Introduction E1 Spread Spectrum Radios has been developed in these recent ten years to a high frequency microwave, digital de/modulation, integrated digital multiplexing, computer control and signal communication technique wholly into Wireless Digital Telecommunication.
E1 Spread Spectrum Radios 2 Features 2.1 E1 Spread Spectrum Radios E1 Spread Spectrum Radios is different from the traditional microwave equipment in smaller size, lighter weight, easy set up and can be conveniently moved from place to place. The main characteristics lie in its advantageous use of high frequency band microwave transmission, digital process, concise structure, quick connection and adapt to complex topographical structure.
E1 Spread Spectrum Radios 2.3 Composition and Principle 2.3.1 System Composition E1 Spread Spectrum Radios is composed of the Outdoor Unit (ODU) and the Indoor Unit (IDU). Other accessories include the antenna systems and terminals. ODU is the Rx/Tx unit of microwave signal. It is composed of microwave components (amplifier, LNA, up/downconverter, frequency synthesizer etc.), duplexer, IF unit (include dual converter, local oscillator, IF processing segment etc.
E1 Spread Spectrum Radios duplexer and are then transmitted out through the antenna system. The opposite terminal’s antenna system receives the microwave signals and passed on to the multiplexer, LNA, downconverter, filter, dual conversion and the IDU. In the IDU, it passes through the QPSK demodulator to recover the microwave frame signal. This frame signal is then processed through demultiplexer to recover the N number of E1 signal and other service signal.
E1 Spread Spectrum Radio s 3 Technological Characteristics Traditional digital microwave equipment generally transmits E1 signal only, so there is always the need to apply for frequency channel use because of technological limitations. In recent years, there is a dramatic change in the structure, composition and application of digital microwave communicative equipment.
