    摘要: A transmitter using a method of block code-based group modulation includes a grouping unit, a generating unit, and a mapping unit. The grouping unit generates symbols by grouping a data bit stream into N-bit groups, and the generating unit generates a codeword set composed of codewords corresponding to combinations of arrangements of pulses that are generated by a result of grouping to a predetermined number. Next, the mapping unit block-maps a codeword selected from the codeword set to groups constituting the symbols.

    摘要: In a local wireless communication system, a reception signal including an STF (short training field) in which a plurality of patterns are repeatedly transmitted is received, the STF including a first number of STF patterns and a second number of STF patterns, the second number of STF patterns having an opposite code to that of the first number of STF patterns. In a first frequency offset estimation and correction process and a second frequency offset estimation and correction process, frequency offset estimation is performed on a plurality of STF patterns to acquire a phase error of each sample constituting the STF patterns, and the frequency of the STF patterns is corrected based on the acquired phase error. Cross correlation is performed on a predetermined number of STF patterns, among a plurality of STF patterns output subsequent to the frequency offset estimation and correction, to detect frame timing.

    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.
