MOBILE TELEPHONE SYSTEM
Document Type and Number:
Japanese Patent JP3127739
Kind Code:
B2
Abstract:
PURPOSE: To prevent deterioration in reception performance and to make possible satisfactory reception by making possible decoding processing suitable for various receiving states.
CONSTITUTION: A base band signal obtained through an antenna 11, RF part 12 and detection part 13 is decoded by a decoding part 14 and converted into an analog voice signal by a CODEC part 15 and a voice is outputted from a speaker 16. In this case, a user selects any one of program ROM 21-23 and mounts it on a connector 20 while considering the change of the current receiving state. The decoding part 14 performs decode processing corresponding to a program arithmetic code read from the program ROM 21-23. Namely, decode processing is executed corresponding to the change of the receiving state when the respective states of radio wave propagation are different such as among the mountains, on a highway or in the city full of buildings.
