Title:
SPREAD SPECTRUM COMMUNICATION EQUIPMENT AND SPREAD SPECTRUM COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP3481471
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain simultaneous transmission and group dependent transmission using a single frequency in the spread spectrum communication.
SOLUTION: As a pseudo noise PN code generated by a PN code generating circuit 18, a PN code for simultaneous transmission that is generated in advance by using bits resulting from each PN code for individual transmission through all communication channels, wherein the bits are majority-decided in the order of transmission, is used, or a PN code for individual transmission that is generated in advance by using bits resulting from each PN code for individual transmission through a plurality of specific communication channels, wherein the bits are majority-decided in the order of transmission, is used. Thus, the equipment similar to that for individual transmission is used to attain simultaneous transmission or group dependent transmission.
