    An improved π/4-quadrature phase-shift keying (QPSK) receiver that incorporates a simple nonredundant error correction (NEC) structure is proposed for satellite and land-mobile digital broadcasting. The bit-error rate (BER) performance of the π/4-QPSK with NEC is analyzed and evaluated in a fast Rician fading and additive white Gaussian noise. (AWGN) environment using computer simulation. It...

    A digital method for generating precisely controlled sine-squared shaped video sync pulses of sixteen different wave shapes is reported. The principle involved in the technique is to store 16 sample values of the desired sine-squared shaped signal in programmable read-only memory (PROM) and to release these digital data sequentially to a digital-to-analog converter at a desired speed to produce th...

    The use of π/4 quadrature phase-shift keying(QPSK) modems for satellite sound broadcast systems (SSBS) broadcasting to mobile or portable receivers is proposed. Three different differential detectors (including the FM-discriminator followed by integrate-sample-and-dump filter) and a novel coherent detector are discussed. The degradation caused by the frequency offset between the local oscillato... View full abstract»

  • The dual green pickup experiment for a compact HDTV color camera with three-2/3 inch CCDs

    A design concept for compact HDTV cameras is proposed. An experimental camera that has been developed in order to verify this concept is described. Since no 2/3-in HDTV charge-coupled devices (CCDs) suitable for compact HDTV cameras have been developed, 2/3-in CCDs (pixels: 766(H)×980(V), aspect ratio: 4:3) developed for a high-quality picture NTSC camera have been used as substitutes. The d... View full abstract»
