摘要： A diversity receiving apparatus for use in an OFDM transmission radio communication/broadcasting system where OFDM signals are received by a plurality of antennas and input into a plurality of receivers. The OFDM received signals are further transformed into frequency spectra. Channel frequency responses are calculated by using OFDM received signal frequency spectra and a reference frequency spectrum generated in a reference spectrum generator. OFDM received signal frequency spectra distortions are compensated by using corresponding channel frequency responses. The transformed OFDM received signal frequency spectra are input into a selector unit as first input signals, while the distortion-compensated OFDM received signal frequency spectra are input into the selector unit as second input signals. The selector unit then selects a second input signal corresponding to a first input signal having maximum amplitude or maximum power. A demodulator then demodulates the output signal of the selector unit into a digital signal sequence.

摘要： According to the present invention, there is disclosed a frame synchronization device which detects a time point to start a data frame from a received signal. Here, the received signal is constituted by disposing the data frame following a preamble period constituted by repeatedly disposing a synchronization symbol. The device stores the synchronization symbol in a memory, and establishes correlation between the synchronization symbol stored in the memory and the received signal by the first correlation processor. The received signal is delayed by a time corresponding to a length of the synchronization symbol by a delay unit, correlation is established between signals before and after the delay by a second correlation processor, and the preamble period is detected from a correlation processing result. The start time point of the data frame is detected based on the correlation processing result of the first correlation processor obtained during the preamble period.

摘要： A file storage apparatus capable of restoring integrity of file management information even when a power supply abnormality occurs without lowering the write speed. When updating meta data stored in an HDD, log data for reconstructing the meta data after update from the meta data before update is written into a non-volatile RAM (NVRAM), then, after this writing is completed, the update is executed. Accordingly, even when the update use meta data temporarily stored in a cache memory is partially lost due to trouble such as a power supply abnormality and when update of the meta data of a hard disk is incomplete, the log data corresponding to the meta data for the update is held in the NVRAM, so it becomes possible to restore the integrity of the meta data on the hard disk by using this log data.

摘要： A transmission channel response calculation section calculates first to n-th transmission channel responses and stores the calculated first to n-th transmission channel responses in a memory section. A correlation calculation section obtains correlation values of the second to n-th transmission channel responses to the first transmission channel responses, respectively, and outputs the obtained correlation values to a transmission channel response synthesis section. The transmission channel response synthesis section gives weights according to the correlation values, weight-synthesizes the first to n-th transmission channel responses, and obtains a synthesized transmission channel response. An influence of noise on the synthesized transmission channel response is reduced. A distortion compensation section eliminates a distortion of the reception signal using the synthesized transmission channel response. Thus, it is made possible to calculate a transmission channel response without being influenced by the noise of a receiver and to ensure eliminating a transmission channel distortion.

摘要： An automatic transmission includes a frictionally engaging element for establishing a predetermined speed range. This predetermined speed range may be a second or higher speed range, and it is set temporarily in N-D squat control and also used for establishing a reverse range. In this transmission, engagement-actuation control of the frictionally engaging element for establishing the predetermined speed range which is executed when a shift is made from a N range to a R range comprises a plurality of control stages. When a shift to the R range is made via the N range following a N-D shift, a shift control apparatus detects the engagement condition of the the frictionally engaging element for establishing the predetermined speed range, selects one of the control stages in correspondence with the engagement condition, and initiates the engagement-actuation control of the frictionally engaging element from the control stage selected, so as to execute an engagement control for establishing the reverse range. Thus, in-gear shifts are executed smoothly without any delay in a N-D-N-R range shift.
