    摘要: In one embodiment, a method of communicating data values over a three conductor interface is provided. Different data values are transmitted by generating and transmitting three respective signals to a receiver using three conductors. The first signal is maintained as a set voltage level. The second signal is alternated between a high voltage and a low voltage according to a carrier frequency. The third signal is alternated between the high and low voltages and is out of phased with the second signal. To transmit a first data value, the first signal is generated on a first conductor, the second signal is generated on a second conductor, and the third signal is generated on a third conductor. To transmit a second data value, the second signal is generated on the first conductor, the first signal is generated on the second conductor, and the third signal is generated on the third conductor.

    摘要: A wireless data receiving apparatus and method using an UltraWide Band (UWB). The apparatus includes a random-interval pulse sequence generator (612); a template pulse sequence generator (621) which generates a reference template pulse sequence used to detect the start point of the random-interval pulse sequence and generates pulse sequences for a signal 0 and a signal 1 by changing the widths of pulses; a random number sequence detector (622) which receives the random-interval pulse sequence and detects information regarding the start point of a random number sequence, using the reference template pulse sequence; and a comparator (623) which compares the pulse sequences for the signal 0 and the signal 1, and determines whether the value of the received random-interval pulse sequence is 0 or 1. Accordingly, it is possible to easily detect information regarding the start point of a pulse sequence while maintaining a processing gain.
