Abstract: A method for compensating changes which would otherwise be produced in a video output signal when the shutter speed exceeds a certain value, even though the same light level of the received image is maintained on the image pickup. In one embodiment, the shutter speed and/or aperture setting are adjusted to compensate. The amplification factor of the output video signal can also be adjusted. In other embodiments, gamma correction is effected separately for each primary color signal to compensate for the changes which affect the color signals in different amounts as the shutter speed is increased.

Abstract: A MIMO receiving apparatus that can demodulate a spatially multiplexed signal without using any division operation requiring a large quantity of operation resources. In the MIMO receiving apparatus, stream separation section (105) separates a spatially multiplexed signal into a plurality of streams based on numerator submatrix A. Numerator submatrix A is determined according to channel matrix H and a canceller scheme and corresponds to a numerator of stream separation matrix S that equalizes the phase and amplitude of the spatially multiplexed signal. Denominator part calculation section (108) calculates a denominator (denominator coefficient) of stream separation matrix S and correction section (117) corrects a threshold determined according to a modulation scheme of the spatially multiplexed signal using the denominator (denominator coefficient) of stream separation matrix S. Demapping sections (109-1 to 109-3) calculate likelihoods of the plurality of streams through a threshold decision using the corrected threshold.

Abstract: Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

Abstract: A partial bit demodulation section that demodulates partial bits among a plurality of bits that form 1 symbol of each modulated signal using a detection method different from likelihood detection, signal point reduction sections that reduce the number of candidate signal points using demodulated partial bits, and a likelihood detection section that obtains received digital signals by performing likelihood detection based on the Euclidian distances between the reduced candidate signal points and a reception point, are provided. By this means, only some bits which are unlikely to be erroneous are found by the partial bit demodulation section, and other bits can be found by the likelihood detection section, enabling bit error rate performances to be effectively improved with a comparatively small computational complexity.
