METHOD AND APPARATUS OF MEASURING THROUGHPUT OF UPLINK DATA IN A WIBRO REPEATER

摘要

A method and an apparatus for measuring throughput of uplink data in a WiBro(Wireless Broadband Internet) repeater are provided to easily measure throughput of uplink data by measuring power of an uplink signal and estimating existence or non-existence of data of each sub-channel. A tile extracting unit(420) collects a certain number of symbols obtained by performing frequency conversion with respect to uplink data and extracts a plurality of tiles. A tile power calculating unit(430) calculates power values of each extracted tile. An average noise value calculating unit(440) calculates an average noise value by using the calculated power value. A threshold value calculating unit(450) calculates a threshold value by reflecting a set value for discriminating a noise through the average noise value. A comparing unit(460) calculates the number of times having a power value exceeding the threshold value among the tiles. A throughput calculating unit(470) calculates throughput by estimating the number of sub-channels having data based on the number of tiles.
