    Abstract: A radar apparatus (1, 1', 1") and a leakage correction method thereof are provided. The radar apparatus (1, 1', 1") includes a transmitter (100, 100') and a receiver (200, 200', 200'-1, 200", 200"-1). The receiver (200, 200', 200'-1, 200", 200"-1) receives transmitting signals (TS) including a sinewave signal (SS1) from the transmitter (100, 100'). The sinewave signal generator (210, 210') of the receiver (200, 200', 200'-1, 200", 200"-1) generates another sinewave signal (SS2) according to the amplitude of the transmitting signals (TS) or received transmitting signals (RTS). The correcting circuit (250) corrects leakage situation (LS) on the received transmitting signals (RTS) according to another sinewave signal (SS2). The phasor of sinewave form corresponding to the leakage situation (LS) relates to the phasor of another sinewave signal (SS2). Accordingly, the performance of receiver (200, 200', 200'-1, 200", 200"-1) may be improved effectively.

    Abstract: A method for providing error-resilient video content may include receiving video data reflective of multiple video frames; encoding the video data to generate a plurality of packets representing a video frame; transmitting the first group of packets to at least two receivers (110); receiving feedback information regarding receiving status of respective ones of the plurality of packets; examining error indications regarding the at least two receivers (110) based on the feedback information and implementing a first error-correction policy if a variation in the error indications among the at least two receivers (110) is below a first error threshold and a second error-correction policy if the variation is above the first error threshold. At least one of the first and second error-correction policies includes transmitting or retransmitting at least one packet using a coding scheme different from a scheme in encoding the plurality of packets already.

    Abstract: A digital phase-locked loop having a phase frequency detector (PFD), a 3-state phase frequency detection converter (3-state PFD converter), a loop filter and a digital voltage-controlled oscillator is provided. The PFD receives an input frequency and a reference frequency and outputs a first signal and a second signal based on the phase difference between the input frequency and the reference frequency. The 3-state PFD converter outputs a 3-state signal according to the first and second signals, wherein the 3-state signal is presented in 1, 0 and -I. The loop filter outputs at least one control bit based on only the 3-state signal. The DCO adjusts the outputted oscillation frequency according to the control bit.
