摘要： In a position detection system utilizing a WLAN supporting multiple data transfer rates, it is possible to reduce the number of required installed base stations, so system construction costs can be lowered. In a wireless station, a transmitted signal is judged at the time of transmission, and in case it is normal user data, the signal is transmitted by setting optimal transmission parameters for which a high communication throughput with wireless communication is obtained, and in case it is a position detection signal, the aforementioned signal is transmitted by setting transmission parameters for which the service range is increased. As a transmission parameter for which the service range is increased, a low data transfer rate or a long preamble length is used.

摘要： A transceiver suitable for larger scale of integration employs direct conversion reception for reducing the number of filters. Also, the number of VCOs is reduced by utilizing dividers to supply a receiver and a transmitter with locally oscillated signals at an RF band. Dividers each having a fixed division ratio are used for generating locally oscillated signals for the receiver, while a divider having a switchable division ratio are used for generating the locally oscillated signal for the transmitter. In addition, a variable gain amplifier for baseband signal is provided with a DC offset voltage detector and a DC offset canceling circuit for supporting high speed data communications to accomplish fast cancellation of a DC offset by eliminating intervention of a filter within a feedback loop for offset cancellation.
