Title:
RECEIVER, COMMUNICATION METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2016189502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a receiver, or the like, in which not only a single target but also multiple targets may be an object, by using a time division spread spectrum code and a frequency division spread code.SOLUTION: A transmission unit 7 included in a transmitter 3 generates a transmission signal by embedding a plurality of TD templates and FD templates based on multiple pairs of time division spread spectrum code and frequency division spread spectrum code, respectively, and transmits to a receiver. The estimation unit 15 of a receiver 5 estimates the Doppler frequency and delay time in a communication path, by utilizing multiple pairs of time division spread spectrum code and frequency division spread spectrum code, and using the whole target space of each pair. Consequently, multiple targets may be an object. Furthermore, estimation is possible in a target space wider than the individual target space, with substantially same acquisition time.SELECTED DRAWING: Figure 1
