摘要： Disclosed is a method for modulating and demodulating data. The method composes symbols by grouping a plurality of symbols for pulse position modulation to newly add symbol compositions to fixed symbols used for the pulse position modulation of the related art. Further, the method uses grouped symbols to improve data transmission rate as the average amount of information increases.

摘要： A modulation apparatus performs modulation in which a signal wave form is positioned at the front part of an entire symbol duration or the latter part of the entire symbol duration based on a first bit of the bit information to generate a modulation symbol including a silent signal duration in which there is no signal waveform. Particularly, the method delays a signal corresponding to a quadrature-phase signal axis by a predetermined time, thereby cancelling a phase difference between symbols.

摘要： A lighting apparatus is disclosed. The disclosed lighting apparatus omni-directionally radiates light emitted from a light emitting diode (LED) in a uniform light intensity. The lighting apparatus may include at least one LED and a reflector to reflect light emitted from the at least one LED. The reflector may include openings that are positioned to correspond to a position of a respective LED. The LED may emit light in a first direction and the reflector may reflect the light in a second direction such that a difference in light intensity at any angle within a first range between 0° to 135° with respect to the first direction is less than or equal 20% of an average light intensity of the entire range, and a light flux within a second range between 135° to 180° is greater than or equal to 5% of the total flux.
