Patent Searching and Data


Title:
TRANSMISSION DEVICE AND COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP3871270
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To enhance tolerance of multi-path delay without lowering transmission efficiency.
SOLUTION: A guard interval insertion processing part 14 determines a specified data rate as a reference data rate and generates a spread signal sequence wherein (n) signals having a data rate (n) (n: an integer of ≥2) times as large as the reference data rate are arrayed in series, and further puts a specified portion of the rear part of the generated spread signal sequence as a guard interval before the spread signal sequence.
