Title: Multi-carrier cdma receiver and transmitter, and transmitting/receiving device
Inventor: HIGASHINAKA MASATSUGU
IPC: H04B1/7087
Filed: 2002-06-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a multi-carrier CDMA (code division multiple access) receiver and transmitter, and a transmitting/receiving which perform synchronous estimation without deteriorating transmission efficiency and efficiently performing high-quality communication.  <P>SOLUTION: A high-frequency analog signal which is multiplied by a spreading code and is assigned to a plurality of sub-carriers is received and is converted into a base band signal by a down converting means, and the high-frequency analog signal is converted into a discrete time signal by an A/D conversion means. Then, the discrete time signal is converted into a frequency domain signal by an FFT (fast Fourier transform) means, and after the spreading code is eliminated by a spreading eliminating section, sub-carriers forming the same information symbol are combined by a data determination means to perform data determination. On the other hand, timing offset estimation between the spreading reception signals from the frequency domain signal after eliminating the spreading code by a synchronization estimating means, and the sample timing of the A/D conversion means and the timing of the FFT transformation means are corrected on the basis of the estimation result.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-07-09
Abstract: <P>PROBLEM TO BE SOLVED: To correct the amount of pilot injection to a proper range by accurately detecting the variation of fuel injection characteristics according to the use period of a fuel injection valve during operation and accurately determining whether the jetted amount of pilot injection is within an allowable value or not.  <P>SOLUTION: This fuel injection control device comprises fuel injection valves 10a to 10d connected to a common rail 3 and injecting fuel to each cylinder of an engine 1 and cylinder pressure sensors 29a to 29d detecting a combustion pressure in each cylinder. An electronic control unit (ECU) 20 performs first and second pilot injections before a main fuel injection from the fuel injection valve of each cylinder. The ECU20 moves the injection timing of a second pilot injection to a timing at which an injection pressure is lowered by the pulsation of a fuel pressure produced by a first pilot injection. The ECU calculates a variation in combustion noise caused by the movement of the injection timing of the second pilot injection based on a combustion pressure detected by the cylinder pressure sensor, determines whether the jetted amount of the pilot injection of each cylinder is appropriate or not based on the variation amount of the combustion noise, and corrects to a proper value if the pilot injection is short.  <P>COPYRIGHT: (C)2004,JPO
