    Abstract: Provided are a pulse-matched filter-based packet detection apparatus and method. The packet detection apparatus includes a photoelectric converter for converting an optical wireless communication signal into an electrical signal, an analog-to-digital converter (ADC) for converting the electrical signal into a digital signal, a pulse-matched filter for outputting a first correlation representing a correlation between a pulse obtained by oversampling a modulated pulse and the digital signal, a correlator for outputting a second correlation representing a correlation between the first correlation and a preamble code, a packet detection signal generator for generating a packet detection signal by comparing the second correlation and a packet detection threshold value, and a demodulator for demodulating the digital signal based on the packet detection signal.

    Abstract: Disclosed herein are an LED lighting control apparatus and an LED lighting control system using the apparatus. The proposed system includes a wired lighting unit connected to LED lighting in a wired manner and configured to perform lighting control on LED lighting. A wireless lighting unit performs lighting control on the LED lighting via wireless communication with a wireless terminal and operates in conjunction with the wired lighting unit. A location communication unit allocates individual IDs of LED lighting and performs transmission/reception of data to/from an external terminal. A multi-sensor unit supports multiple sensors and analyzes sensor data collected from the multiple sensors. An active heat dissipation unit dissipates heat from the LED lighting based on analyzed sensor data. A processor control unit controls operations of the wired lighting unit, the wireless lighting unit, the location communication unit, the multi-sensor unit, and the active heat dissipation unit.
