5.8GHz PDH User’s Manual 1. Introduction PDH, Plesiochronous Digital Hierarchy, 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 a wireless digital signal communication mode.
5.8GHz PDH User’s Manual 2. System Basic Features 2.1 PDH System PDH system 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 (above 5.7GHz frequency), digital transformation, concise structure, quick connection and adapt to complex topographical structure.
5.8GHz PDH User’s Manual 2.3 Composition and Principle 2.3.1 System Composition PDH system is composed of ODU and IDU. Other set of equipments include antenna system, end- terminals etc. ODU unit is the Rx/Tx unit of microwave signal. It is composed of other microwave units (amplifier, converter, coded integrator etc.), duplexer, IF unit (dual converter, local oscillator, IF processing segment etc.), monitor unit, remote unit, and power board.
5.8GHz PDH User’s Manual 2.3.2 System Principle N number of E1 signals, digital service, 9600b/s system net control and 9600b/s computer data communication etc. multiplexed in a multiplexer to a specific microwave frame code. After QPSK modulation, the system sends the transmission to the ODU through only one IF cable.
5.8GHz PDH User’s Manual 3. Technological Characteristics Traditional digital microwave equipment generally transmits E1 signal only, so there is always the need to apply for frequency channel because of technological limitations. In recent years, there is a dramatic change in the structure, composition and application of digital microwave communicative equipment.

5.8GHz PDH User’s Manual Appendix G: RSL Calculation and Link Budget The received signal level (RSL) can be estimated using the following formula: RSL (dBm) = Pout – FL1 + G1 + G2 – FL2 – LP where: Pout is the transmitter output power (in dBm) FL1 is the feeder loss of the transmit side (in dBm) G1 is the gain of the transmit antenna (in dB) G2 is the gain of the receive antenna (in dB) FL2 is the feeder loss of the receive side (in dB) LP is the Path loss, defined by: LP (dB) = 96.
