摘要： An interface circuit for data transmission and the method thereof is described. The interface circuit includes a transmitter providing data through first data signals during the data periods corresponding to rising and falling edges of a clock signal, a transition detection unit selectively asserting a detection signal in response to the number of the first data signals having transitions between every two adjacent data periods, a transition reduction unit generating second data signals by outputting the inverted and non-inverted first data signals respectively when the detection signal is asserted and de-asserted, and a receiver restoring the data from the second data signals and the detection signal.

摘要： A channel estimator for use in wireless local area networks (WLAN's), characterized in that a channel estimation controller with a simplified recursive least square (RLS) algorithm and a data-reconstructor are employed to adjust the channel response in frequency domain during the delivery of a signal packet. Such adjustment is adaptively performed at anytime during the delivery of a signal packet so as to achieve fast convergence as well as accurate channel estimation.

摘要： A frequency offset compensation estimation system and method for a wireless local area network. First, a preamble sequence of a frequency package is sent to a frequency offset estimation (FOE) device so that an initial frequency offset signal amount is obtained and sent to the frequency offset compensation (FOE) device for compensation. Then, the compensated signal is sent to a frequency offset residual phase estimation (FOS RPE) device so as to calculate an offset amount of the frequency and send it to the frequency offset residual phase compensation (FOS RPC) device for compensation. The present invention mainly employs a residual frequency offset estimation device (Residual FOE device) to estimate the residual frequency offset signal of each of the frequency signals compensated by the frequency compensation device and feedback it to the frequency compensation device for compensation. Therefore, the operation load of the frequency offset residual phase compensation (FOS RPC) device will be reduced so as to improve the operation efficiency of the system.
