Title:
RADIO TRANSMITTER, RADIO RECEIVER AND RADIO TRANSMISSION METHOD
Document Type and Number:
Japanese Patent JP3704127
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a signal transmission method in the CDMA mobile communication system, which is capable of preventing the generation of a hearing aid, by providing a large spread rate for each radio frame as a transmission information amount of temporary transmission is smaller and occasionally transmitting the frame with a smaller transmission power.
SOLUTION: When regular transmission information and occasional transmission information, which form transmission data are inputted into a radio frame configuration section 3 and a transmission information amount detection section 1, the section 1 detects the information transmission amount of the occasional transmission information and supplies the detection result to a control section 2. The section 2 controls the section 3, a spread section 5 and an amplifier section 6 so that the number of bits in a radio frame becomes smaller, dis-persion rate becomes larger, and the amplification amount is increased for a prescribed period so that the information amount for the prescribed period is smaller, on the basis of the detection result of information transmission amount.
