Abstract
A radio communication system minimizes power consumption against noises. The system includes a first radio terminal (A) with a first transmitter (A) for transmitting a first data indicative of a specific event, and a second radio terminal (A) with a battery (B) and a receiver (B). The first radio terminal (A) includes a first bit interpolator (A) which inserts a check bit pattern of '01010101' at a predetermined cycle into one frame of the first data. The second radio terminal (B) has a second power controller (B) which intermittently activates the second receiver (B) at predetermined intervals in order to receive the bit-interpolated data from the first transmitter. A check bit detector (B) is included in the second radio terminal (B) to detect the check bit pattern from within the bit interpolated data and to issue a stop signal immediately upon occurrence of that the check bit pattern fails to appear at said predetermined cycle within a predetermined time frame shorter than one frame length of the first data. In response to the stop signal, the power controller of the second radio terminal terminates a current receiving operation.
