Title:
DIGITAL CORDLESS TELEPHONE SYSTEM
Document Type and Number:
Japanese Patent JP3192871
Kind Code:
B2
Abstract:
PURPOSE: To perform sure communication even when signals transmitted from a call origination side terminal leak out to an adjacent channel other than a call origination channel in the inter-slave-unit direct communication function of a PHS (Persional Handy Phone System).
CONSTITUTION: This system is provided with a local oscillation signal generation circuit 4, a code identification circuit 6 for reading data outputted by demodulating radio signals inputted from a reception antenna 2 in a demodulation circuit 3 by using local oscillation signals and judging whether or not an incoming identification code included in the data is transmitted toward a present terminal, a reception level detection circuit 7 and a memory 8 for storing the code identified results and reception level detected results of the entire communication channels successively demodulated by the demodulation circuit. A channel with the highest reception level in the communication channels transmitted to the present terminal is selected from the code identified results and the reception level results by a channel selection circuit 5 and the local oscillation signal generation circuit 4 is informed of a channel number.
