Abstract: A proximity sensor having improved environmental compensation performance and an environmental compensation method in the proximity sensor are disclosed. The environmental compensation method and the proximity sensor advantageously reduce processing time, algorithm operation time, and power consumption by previously setting sensing values before sensing of sensors unlike a typical method in which compensation is carried out by multiplying factors obtained through software. Further, the environmental compensation method and the proximity sensor have an advantage of accurate compensation not only for linearly varying environmental factors but also non-linearly varying environmental factors.

Abstract: The present invention relates to a method of detecting an access address of a physical channel in a Bluetooth signal to which channel coding is applied, the method including: performing initial signal processing in a unit of a specific length in a preamble section of a Bluetooth signal; and performing channel decoding in the specific length for a preamble part remained after the initial signal processing, wherein the specific length is a bit pattern length of a bitstream which is repeated in the preamble section or a length of a bitstream input for channel decoding. According to the present invention, channel decoding is performed in a unit of a bit pattern length of an access address from the remaining preamble part, and thus detection of the access address is available even though a start point of the access address is not provided.

Abstract: A receiver performs independent packet detection using synchronization words with orthogonality when multiple signals on which frequency-shift keying is performed coexist. The receiver includes a frequency demodulator generating a quasi-amplitude modulation signal that has a value proportional to frequency shift from the first signal or second signal being received, a sign discriminator discriminating a sign of the generated quasi-amplitude modulation signal, and a multi-binary correlator calculating a first correlation value which is a binary correlation value between the discriminated sign and a first synchronization word and calculating a second correlation value which is a binary correlation value between the discriminated sign and a second synchronization word.

Abstract: Disclosed herein are a Bluetooth signal receiving device and method. The Bluetooth signal receiving device includes an energy detector circuit, a radio frequency (RF) power detector circuit, an analog-digital converter circuit, and an automatic gain control circuit. The energy detector circuit detects a significant signal, having energy higher than background noise by a threshold value or more, from a received signal. The RF power detector circuit detects the magnitude of the received signal. The analog-digital converter circuit converts the analog value of the received signal into a digital value, and outputs the digital value. When the significant signal is detected, the automatic gain control circuit determines any one of predetermined coarse gain intervals to be a first coarse gain interval of the received signal by taking into account the magnitude of the received signal detected by the RF power detection circuit.
