RECEIVER, WIRELESS COMMUNICATION SYSTEM, AND RECEIVING METHOD
First Claim
1. A receiver that receives a radio signal transmitted from a transmitter, comprising:
- a receiving unit that receives a signal that is wirelessly transmitted from the transmitter at one of a plurality of transmission frequencies;
a receiving frequency change determining unit that determines whether a receiving frequency is to be changed, based on the signal received by the receiving unit; and
a communication error acceptance time setting unit that sets an acceptance time as a period of time for which communication errors after confirmation of a receiving operation are accepted, based on the signal received by the receiving unit, whereinthe communication error acceptance time setting unit sets the acceptance time to different periods of time, depending on whether the receiving frequency change determining unit determines that the receiving frequency is to be changed.

Abstract
A receiver (200) that receives a radio signal transmitted from a transmitter includes a receiving unit (2042) that receives a signal that is wirelessly transmitted from the transmitter at one of a plurality of transmission frequencies, a receiving frequency change determining unit (2048) that determines whether a receiving frequency is to be changed, based on the signal received by the receiving unit, and a communication error acceptance time setting unit (2046) that sets an acceptance time as a period of time for which communication errors after confirmation of a receiving operation are accepted, based on the signal received by the receiving unit. The communication error acceptance time setting unit sets the acceptance time to different periods of time, depending on whether the receiving frequency change determining unit determines that the receiving frequency is to be changed.

7. A signal receiving method according to which a receiver receives a radio signal transmitted from a transmitter, comprising:
-
receiving a signal that is wirelessly transmitted from the transmitter at one of a plurality of transmission frequencies; determining whether a receiving frequency is to be changed, based on the received signal; and setting an acceptance time as a period of time for which communication errors after confirmation of a receiving operation are accepted, based on the received signal, wherein the acceptance time is set to different periods of time, depending on whether it is determined that the receiving frequency is to be changed.
