摘要
This invention relates to each of the route characteristic correction method of receiving and transmitting a wireless space channel measuring device. ; radio path of the receiving space in the channel measurement device characteristic correction method, N of the spread spectrum signal received via the transmitter and M receive antennas for transmitting a spread spectrum signal via the transmission antenna in accordance with the present invention From the plurality of digital data converted into the wireless space channel to the measuring device comprises a receiving unit for storing, by connecting each of the N transmit antennas and a single transmit antenna M receive antennas of the M to M wire cable forming the wire path, wired back-to-back and the process of performing the test; Wired back-to-back i of the plurality of digital data are stored in the receiving unit through the test (where, i is a natural number 1 i M) and the process of separating the i-th digital data corresponding to the second wire receiving path; Decimating the digital data separate i-th, performs the sliding nose illustration for the decimated data and extracting the time delay; From the decimated samples to extract the sample after the time delay includes the step of extracting the attenuation characteristic and the phase characteristic of the i-th path receiver cable. ; On the other hand, the wireless space channel measurement according to the invention path of the transmission characteristic correction method in the unit, will be omitted because the same technical features and characteristics of the path correction method of the receiver. ; wireless space channel, cable back- -to-back (back-to-back).
