MULTI ANTENNA RADIO CHANNEL MEASUREMENT APPARATUS USING MULTI CODE AND OPERATING METHOD THEREOF

摘要

PURPOSE: A multi-antenna wireless channel measurement device using multiple codes and an operation method thereof are provided to measure a wireless channel by transmitting codes for measuring various lengths based on the speed change of a mobile unit. CONSTITUTION: A timing unit(110) generates a code clock synchronized with other wireless channel measurement device and a synchronization signal. The timing unit determines code and measurement time for measurement according to the speed of an installed mobile unit in which a wireless channel measurement device is installed. A baseband unit(120) successively transmits codes for the measurement according to the synchronization signal. The baseband unit stores wireless channel measurement data by receiving the wireless channel measurement data in the measurement time. An RF(Radio Frequency) module(130) transmits the code for the measurement through a multi-antenna. The RF module receives the wireless channel measurement data.
