Title: Channel estimation device using time-multiplexed pilot symbols and traffic symbols in mobile communication system
Inventor: LEE GEUM OK
IPC: H04B1/76
Filed: 2002-01-14
Abstract: PURPOSE: An apparatus for estimating a channel using time-multiplexed pilot and traffic symbols in a mobile system is provided to combine a reference phase signal obtained from a modulated traffic with a reference phase signal calculated from a pilot signal in estimating a channel so that the performance of channel estimation can be maintained even though a fading frequency is increased. CONSTITUTION: The apparatus for estimating a channel using time-multiplexed pilot and traffic symbols in a mobile system consists of a multiplier(100), a switch(200), a traffic channel parameter estimation part(300), a pilot channel parameter estimation part(400), and an adder(500). The multiplier(100) multiplies a received signal(r(t)), containing both a traffic symbol and a pilot symbol, by the PN code(gm(t)) of the Ith path, despreads it, and outputs the despread signal(rI(m,n)) to the switch(200). The switch(200), if the output signal of the multiplier(100) is the traffic symbol, passes it to the traffic channel parameter estimation part(300). Meanwhile, if the output signal of the multiplier(100) is the pilot symbol, passes it to the pilot channel parameter estimation part(400). The traffic channel parameter estimation part(300), if the traffic symbol is inputted from the switch(200), estimates the traffic channel parameter of the Ith path using the traffic symbol and outputs it to the adder(500). The pilot channel parameter estimation part(400), if the pilot symbol is inputted from the switch(200), estimates the pilot channel parameter of the Ith path using the pilot symbol and outputs it to the adder(500). The adder(500) combines the estimated traffic channel parameter with the estimated pilot channel parameter, creates the final channel parameter, and outputs it to a rake receiver(1).

Title: Carrier Recovery Apparatus of VSB Receiver and A method for recovering carrier using thereof
Inventor: KIM GI BEOM
IPC: H04L27/06
Filed: 2002-01-29
Abstract: PURPOSE: A device and method for restoring carriers in a VSB broadcasting signal receiver are provided to smoothly perform restoration of carriers in the case that a pilot signal is damaged temporarily or periodically in a flexible channel environment. CONSTITUTION: A carrier restoring device in a VSB broadcasting signal receiver includes the first and second low pass filters(210,250), a limiter(230), a multiplier(190), a numerically controlled oscillator(280), and a frequency error provider(260). The first low pass filter produces a carrier varied with frequency offset through pilot tone included in I-signal of a VSB broadcasting signal. The limiter limits the magnitude of the carrier produced by the first low pass filter. The multiplier multiplies the magnitude of the carrier by Q-signal of the VSB broadcasting signal. The second low pass filter extracts a DC component corresponding to a frequency error of the carrier from the multiplied result. The numerically controlled oscillator generates a complex carrier corresponding to the DC component. The frequency error provider stores the DC component, and provides the DC component to the numerically controlled oscillator when pilot included in the I-signal is damaged so that the pilot tone is distorted.
