发明名称 Apparatus for measuring multipath propagation characteristics
摘要 An apparatus for measuring multipath propagation characteristics receives a plurality of transmitted waves propagated over a plurality of different propagation paths and subjected to multipath fading over the propagation paths, and measures multipath propagation characteristics with respect to those propagation paths based on the received waves. The multipath propagation characteristics can be measured relative to a plurality of propagation path systems using the same frequency band. The apparatus for measuring multipath propagation characteristics comprises a plurality of transmitters located in different spatial positions, respectively, and a receiver for receiving a plurality of waves transmitted from the transmitters while the receiver is moving. The transmitters generate respective waves to be transmitted that each comprise a plurality of discrete spectral components which are arranged in the frequency domain such that they do not overlap each other in the same frequency band. The receiver simultaneously receives the waves which have been transmitted from the respective transmitters and each propagated over a plurality of different propagation routes or paths while being subjected to multipath fading, and measures multipath propagation characteristics relative to the propagation paths based on the received waves.
