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： 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.

摘要： Implant devices, systems, and methods are used to prevent post-surgical dislocation of a surgically reconstructed ball-and-socket joint, while retaining the patient's range of motion. The implant device can have a cup having a substantially hemispherical inner contour; a head at least partially inserted within the cup, the head having an outer contour that is generally spherically-shaped, and an elastic retainer with an inner contour that is at least a cross-sectional segment of a spherical shape having substantially a same radius as the inner contour of the cup, the elastic retainer being attachable over an open end of the cup to retain the head within the cup and allowing the outer contour of the head to freely rotate and/or pivot against the inner contour of the cup over the predetermined range of motion of the ball-and-socket joint.
