20110206105METHOD FOR DETERMINING HYBRID DOMAIN COMPENSATION PARAMETERS FOR ANALOG LOSS IN OFDM COMMUNICATION SYSTEMS AND COMPENSATING FOR THE SAME - In a transmit/receive system, the carrier frequency offset (CFO), I/Q imbalance, and DC offset (DCO) can cause serious signal distortions. These analog losses can be compensated for individually or in combination of any two of them by following various methods that have been suggested. However, there have suggested no methods of simultaneously compensating, for these three types of losses that occur in actual devices at the same time. The present invention suggests a novel pilot signal that has a cyclic signal portion and a portion of two equally spaced continual signals. The invention provides a method for compensating for the CFO, I/Q imbalance, and DCO by simultaneously performing the time domain compensation and the channel estimation using those signal portions. The method also compensates for the I/Q imbalance and the channel response on the transmitter side in the OFDM scheme.08-25-2011

In the model creating step, the local descriptor to be used in the model is selected based on the contributions of the individual vectors which are evaluated in such a way that when a vector extracted from one image of one three-dimensional object is an approximate nearest neighbor to another vector relating to an image of the three-dimensional object seen from a different viewpoint, the vector has a positive contribution, whereas when the vector is an approximate nearest neighbor to another vector relating to a different three-dimensional object, the vector has a negative contribution.

20100246723METHOD FOR ESTIMATING AMOUNT OF DISTORTION IN CFO AND DCO, METHOD FOR COMPENSATING RECEIVED SIGNALS USING THE SAME, AND RECEIVER - A received signal delivered through a transmission line can be compensated for CFO and DCO to improve the SNR of the received signal, eventually resulting in an effective improvement in the error rate. In this context, methods for estimating and compensating for CFO and DCO have been studied, for example, using pilot signals or a blind method. However, the methods would require a huge amount of calculations for the estimation of CFO in the presence of DCO, as with the ML method, or never essentially eliminate errors from an estimated value. The received signal has convoluted influences through the transmission line, so that observation of the continual symbols of periodic pilot signals on the frequency axis shows just a phase shift by the CFO. Therefore, the CFO can be analytically found from the continual symbols of periodic pilot signals, thereby allowing the DCO to be estimated and both the CFO and the DCO to be compensated for.09-30-2010

20100208783METHOD FOR CALCULATING CFO AND I/Q IMBALANCE COMPENSATION COEFFICIENTS, COMPENSATION METHOD USING THE SAME, AND METHOD FOR TRANSMITTING PILOT SIGNAL - The OFDM scheme based communication system is currently being put into practical use because of its effective use of frequencies and its enhanced resistance to multipath. However, since the OFDM scheme treats multiplexed signals with overlapped spectra, the orthogonality between carriers are corrupted and the error rate characteristic is degraded in the presence of CFO. Furthermore, since locally oscillated signals different by a phase of π/2 are difficult to obtain in demodulating the I/Q signal, an imbalance is caused between the I/Q signals, resulting in degradation in the error rate characteristic. The invention suggests a novel pilot signal, and a method for analytically determining compensation values for CFO and I/Q imbalance and compensating for those distortions using the resulting values. Furthermore, the invention is applicable not only to the OFDM scheme but also to any protocol that involves pilot signals.08-19-2010

The pressure of the high temperature high pressure water may be not lower than the saturated water vapor pressure at the temperature, i.e., a pressure at which the liquid state is maintained.07-29-2010
20100177851COMPENSATION METHOD, PROGRAM, RECORDING MEDIUM, AND RECEIVER FOR OFDM SIGNAL HAVING CFO AND DCO - A frequency offset (CFO) and a direct current component offset (DCO) occur in an OFDM scheme signal. To address this, such a method has been suggested which allows a pilot signal to be mixed with a communicated signal for compensation. However, if the pilot signal has a long duration, then a compensation method without the pilot signal is required to compensate signals during that period. However, no such a method is conventionally available which compensates for both the CFO and DCO without the pilot signal. Using the orthogonality of the OFDM signal, the matrix of a system in which CDO and DCO have occurred is subjected to the singular value decomposition, thereby predetermining the CFO candidate value which allows for demodulating zero from the received signal and an array of numerical values of CFO check data. Then, in a compensation section (17), the received signal is successively multiplied by the numerical values. The typical CFO value provided when the minimum value has been demodulated is outputted as an estimate value for compensation.07-15-2010
