US 2009/0221237 A1 · Data sending and receiving apparatus and method

Abstract

A data sending and receiving apparatus includes a sending state acquiring unit that monitors and acquires at least one of a sending process state indicating whether the sending process of the transmission data is being executed, and a signal strength of the transmission data; a signal strength measuring unit that measures a signal strength of the reception data; a measured value correcting unit that corrects a measured value of the signal strength of the reception data measured by the signal strength measuring unit, in accordance with at least one of the sending process state and an acquisition result of the signal strength of the transmission data acquired by the sending state acquiring unit; and a demodulating unit that demodulates the reception data using a corrected measured value corrected by the measured value correcting unit.

Dependent claims

A data sending and receiving apparatus, interposed between a terminal device and a communication device, that sends transmission data received from the communication device and addressed to the terminal device, and sends reception data from the terminal device to the communication device after demodulating, the data sending and receiving apparatus comprising:

a sending state acquiring unit that monitors and acquires at least one of a sending process state indicating whether the sending process of the transmission data is being executed, and a signal strength of the transmission data;
a signal strength measuring unit that measures a signal strength of the reception data;
a measured value correcting unit that corrects a measured value of the signal strength of the reception data measured by the signal strength measuring unit, in accordance with at least one of the sending process state and an acquisition result of the signal strength of the transmission data acquired by the sending state acquiring unit;
and
a demodulating unit that demodulates the reception data using a corrected measured value corrected by the measured value correcting unit.
