Title: Transmitter and transmitting method
Inventor: SUDO HIROAKI
IPC: H04J11/00
Filed: 2002-11-18
Abstract: <P>PROBLEM TO BE SOLVED: To prevent increase of the transmission delay due to an excessive increase of the number of times of retransmissions, almost without decreasing the transmission efficiency.  <P>SOLUTION: A control unit 101 outputs retransmission information about whether a transmission signal is a retransmission signal or not and about how many times the signal is retransmitted, when the transmission signal is a retransmitted signal to a selecting unit 107. A spread unit 102 applies spread processing to the transmission signal. An IFFT unit 103 applies orthogonal frequency division multiplex processing to the transmission signal. A GI insertion unit 104 inserts a guard interval in the transmission signal. A GI insertion unit 105 inserts a guard interval longer than the guard interval inserted by the unit 104 into the transmission signal. A GI insertion unit 106 inserts a guard interval longer than the guard intervals inserted by the units 104, 105 in the transmission signal. The unit 107 selects a transmission signal, in which a longer guard interval is inserted as the number of retransmission increases, on the basis of the retransmission information inputted from the unit 101.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To reduce low frequency moire in secondary and ternary colors caused on a four color screen.  <P>SOLUTION: A relation is satisfied between at least two dot screens 200a and 200b in dot screens in four colors, wherein one of two screen vectors wa2, wb2 match with each other and the other does not match. The dot screen 200a is a tetragonal lattice screen and the screen vector wa2 is perpendicular to a base vector ra1. The dot screen 200b is an orthorhombic lattice screen and the screen vector wb2 is perpendicular to a base vector rb1. The matching between the screen vectors wa2, wb2 indicates that the spatial frequency spectrums corresponding to the vectors match with each other. Since the spatial frequency spectrums of a set can be made to match between two colors, it results in that the interval between the remaining 4-color spatial frequency spectrums is made wider to reduce low frequency moire.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
