Granted: 1998-05-05
Abstract: In a digital radio-relay system having a transmitting terminal  station  (10),  at least  one  repeater  station (100),  and a receiving terminal station (50), a  repeater station (100) is a non-regenerative repeater station which does not regenerate a digital signal in order to  simplify and  reduce  cost of the system, while  keeping  excellent signal quality in transmission. Each repeater station  has a plurality of sub-units relating to respective sub-system signals  each having a plurality of carriers (A, B, C)  so that  frequency  spectrum  of each  sub-system  signal  is allocated on frequency axis based upon frequency  division multiplex  system. A repeater station (50) having a  first frequency  converter  (112)  to  convert  received   radio frequency  to  IF frequency, bandpass  filters  (132)  for deriving  one  of carriers (A, B, C) in  each  sub-system signal,  amplifiers (134) to amplify thus derived  carrier (A,  B,  C)  on  IF band stage,  and  a  second  frequency converter  (138)  to  convert the IF  frequency  to  radio frequency,  has a common reference oscillator (104)  which generates  reference  frequency which is common divisor of all the local frequencies for all the radio frequencies of all  the  sub-system  signals,  and,  only  one  of  upper heterodyne signals and lower heterodyne signals are  taken in  all the frequency conversions, so that  distortion  in each  relay  section is added in-phase,  and  that  leaked noise  (A',  B', C') caused by said  bandpass  filters  is added  to  original carrier (A, B, C)  in-phase.  All  the distortion  thus  added  in  the  relay  sections  can  be compensated. by  a  transversal  equalizer  (65)  in   the receiving  terminal station. Therefore,  excellent  signal quality  is  obtained although a  simple  non-regenerative repeater station is used.

Filed: 1995-01-30
Granted: 1999-12-28
Abstract: Electric field intensity of a signal corresponding to a plurality of receivers and received through antennas are converted into direct currents. The converted durect currents thus converted are fed to electric field level detection circuit. The electric field level detection means detects the electric field level on the basis of the direct currents of respective receivers and feeds a detection signal to a control portion. The control portion compares the electric field level corresponding to the direct current value in said controller with a predetermined electric field level to make judgement that the received electric field is a strong electric field and stable. Then, a command is issued to keep one of the receivers, at which the higher electric field level is detected and to turn off other receiver. An electric power source control portion performs switching of the switch portions corresponding to respective of the receivers to supply only one of the receiver from a power source and to block power supply from the power source to other receivers.
