摘要： A robust timing offset compensation scheme for multi-carrier systems. According to the invention, a timing offset compensator is provided to compensate a current symbol in the frequency domain for the effect of timing offset with a timing offset prediction value. Then a timing error estimator calculates a timing error value for the current symbol based on a function of a phase tracking value, a channel response of each pilot subcarrier, transmitted data on each pilot subcarrier, and a timing compensated version of the current symbol on the pilot subcarrier locations. Furthermore, a timing tracking unit receives the timing error value of the current symbol to generate a shift amount of the DFT window and the timing offset prediction value for a next symbol.

摘要： An OFDM detection apparatus and method for networking devices. First, a sample sequence is taken from the beginning of a newly arrived network packet. Next, a first correlation sequence between the complex conjugate of the sample sequence and the sample sequence with a lag of N samples is formed. In the meantime, a second correlation sequence between the complex conjugate of the sample sequence and the sample sequence with a lag of M samples is also formed. The first and the second correlation sequence are then normalized. Depending on a comparison between the first normalized correlation sequence and a first predetermined threshold as well as another comparison between the second normalized correlation sequence and a second predetermined threshold, the newly arrived network packet is determined accordingly whether it is an OFDM modulated packet.

摘要： The invention discloses a finite impulse response (FIR) filter for processing a digital input signal to generate a digital output signal. The FIR filter has a tap amount N and a decimation ratio D. The FIR filter includes a first memory, a multiplier, and an accumulation module. For each input sample of the digital input signal, the first memory provides N/D corresponding tap coefficients from a plurality of tap coefficients in turn. The multiplier multiplies the input sample with the N/D corresponding tap coefficients in turn to generate N/D product values. The accumulation module adds the N/D product values to N/D previous accumulation values to generate N/D renewed accumulation values respectively. If one of the accumulation values has already accumulated N product values, the accumulation module outputs the accumulation value as an output sample of the digital output signal.

摘要： A frequency offset estimation apparatus for intersymbol interference channels. A storage area having M elements is provided to shift a received sample sequence by M samples to generate a lagged sample sequence. A sequence of preliminary values is calculated by differential operation between the received sample sequence and the lagged sample sequence. Next, a summation of the power of the preliminary value sequence over M′ samples is taken to obtain an accumulative sum. Finally, the angle of the accumulative sum is derived and then scaled by a factor. A frequency offset estimate for the received sample sequence is thus obtained.
