WIRELESS RECEIVING APPARATUS AND METHOD

摘要

According to one embodiment, a wireless receiving apparatus includes a detector, a demodulator, a determination unit and a setting unit. The detector detects a wireless frame which has a received power level higher than a carrier detection threshold when the wireless frame is received. The determination unit determines a connection status in accordance with whether or not the demodulation is successful. The setting unit sets the carrier detection threshold at a first threshold if the connection status is an initial status where demodulation of a connection request frame is not successful, and which sets the carrier detection threshold at a second threshold if the connection status is other than the initial status, the second threshold being a variable value and larger than the first threshold.

1. A wireless receiving apparatus, comprising:
a detector which detects a wireless frame which has a received power level higher than a carrier detection threshold when the wireless frame is received; a demodulator which performs demodulation on the wireless frame; a determination unit which determines a connection status between the wireless receiving apparatus and another apparatus in accordance with whether or not the demodulation is successful; and a setting unit which sets the carrier detection threshold at a first threshold if the connection status is an initial status where demodulation of a connection request frame is not successful, and which sets the carrier detection threshold at a second threshold if the connection status is other than the initial status, the first threshold being a fixed value, the second threshold being a variable value and larger than the first threshold.
