摘要： A light emitting device of the present invention includes at least: at least more than one blue light chip, at least more than one red light chip and a fluorescent layer overlaid and bonded to the blue light light chip and the red light chip. The fluorescent layer is formed from a uniform mixture of a yellow phosphor and a red phosphor with the addition of a transparent plastic material. At least one portion of the absorbed light source is used to emit a light source with a wave length dissimilar to the wave length of the absorbed light or of the same wave length, thereby achieving the effectiveness to increase the illuminance and color rendering of white light.

摘要： A transmitter and the method therefor are provided. The transmitter is applied in an orthogonal frequency division multiplexing (OFDM) based or other multicarrier communication systems. The transmitter uses N sub-carriers. Among the N sub-carriers, L sub-carriers (or tones) are reserved for PAPR reduction. L is less than N. The method includes the following steps. Original frequency domain data symbols are generated and fed into the reserved-tone symbol generation unit. The reserved-tone symbols are generated by using pure frequency domain signal processing. Then the reserved-tone symbols are combined with original data symbols to generate combined PAPR reduction signal. The resultant PAPR reduction signal can be fed into reserved-tone symbol generation unit iteratively to obtain updated reserved-tone symbols. For proper iterations, the original data symbols combined with L frequency domain reserved-tone symbols will result in lower PAPR transmit signal.
