摘要： A novel transceiver structure is proposed to increase the achievable data rate for ultra wideband transmitted reference (UWB-TR) systems. For every Ns pulse pairs during one symbol transmission, the data pulses are weighted by one of the M-ary orthogonal sequences, thus carrying additional log2 M-bit information. Furthermore, by utilizing a pair of balanced matched filters before the cross correlator, the minimum separation between the reference and data pulses is significantly reduced without causing any inter-pulse interference (IPI), which in turn reduces the minimum required frame length in order to avoid the inter-frame interference (IFI). As a result, the invented TR system can achieve higher data rates than the conventional TR system, while maintaining superior bit-error-rate (BER) performance even with lower transmit power.

摘要： The present invention relates to a UWB distance measurement system and method of driving the system. The system includes a reception antenna for receiving a signal, which is output from a transmission unit, is reflected from a target and is incident on the reception antenna, a UWB amplifier for amplifying the received signal and generating a first signal, a reference waveform generator for generating a reference waveform which is a reference for analysis of the first signal, a window function generator for generating at least one window function that is applied to the first signal, a correlator for correlating the first signal with the window function output from the window function generator, and generating a second signal which is a revised frequency response of the first signal, and a delay time detector for detecting a delay time component in the second signal.

摘要： Disclosed herein is an Ultra WideBand (UWB) M-ary Code Shift Keying (MCSK)/Binary Pulse Position Modulation (BPPM) wireless communication system and method. The system includes a transmitter and a receiver. The transmitter selects a specific TH code using MCSK according to an additional data stream, performs BPPM on a desired signal according to the selected TH code, and transmits the modulated signal via a channel. The receiver receives the signal transmitted from the transmitter via the channel, and estimates the transmitted signal, which is transmitted from the transmitter, through detection of a Maximum Likelihood (ML) sequence.
