    摘要: A provisional symbol discrimination timing detection unit detects a provisional symbol discrimination timing of a received signal modulated by a multi-subcarrier modulation scheme. A provisional symbol extraction unit demodulates the received signal and outputs, as a provisional demodulated symbol, a demodulated signal value of the provisional symbol discrimination timing of the demodulated signal for each subcarrier, demodulated signal being obtained by quadrature-demodulating the received signal. A phase difference detection unit detects a phase difference between the phase of the output provisional demodulated symbol of the received signal at a predetermined position and the phase of a reference symbol at this position. A symbol discrimination timing correction unit obtains a time difference between the provisional discrimination timing and the reference symbol discrimination timing on the basis of a subcarrier frequency and the detected phase difference for each subcarrier and corrects the provisional symbol discrimination timing on the basis of the time difference.

    摘要: An illuminating apparatus comprises a first optical integrator and a second optical integrator which are replaceably arranged. The second optical integrator is structured to provide substantially the same number of secondary light sources as the first optical integrator but with the different size of surface light source formed by these second light sources. Further, the structure is arranged so that it has an aperture number on the emission side, which is equal to the aperture number of the first optical integrator on its emission side. Hence, the illuminance evenness is not degraded even when the .sigma. value is significantly varied.
