摘要： Disclosed herein is a hybrid channel estimation method and system for an Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system. The hybrid channel estimation method includes the steps of acquiring a first channel coefficient using decision-directed channel estimation; acquiring a second channel coefficient using pilot-symbol-aided channel estimation; and calculating the final channel coefficient of a received signal by multiplying the first and second coefficients by first and second multiplication coefficients, respectively, and adding the multiplication results. The step of acquiring the first channel coefficient using the decision-directed channel estimation includes the steps of acquiring an initial channel coefficient by processing a long training symbol using a Least Square (LS) method; generating data by equalizing, demodulating and modulating a fast Fourier transformed new symbol using a previously estimated channel coefficient; and acquiring a new channel coefficient by dividing the new symbol by the data.

Hence, by means of the state machine for the IEEE 802.15.4 PHY, the IEEE 802.15.4 physical layer operation state can be controlled to optimize the operations of the upper MAC.

摘要： The present invention relates to a method and apparatus for detecting STBC-OFDM signals in time-variant channels. The method includes a step of demodulating STBC-OFDM modulation signals into OFDM reception symbols using Fast Fourier Transform (FFT); a step of estimating a frequency response for each sub-channel; an STBC decoding step of calculating decision variables determining the A transmit data symbols that are transmitted during the B OFDM symbol periods for each sub-channel; and a step of determining the transmit data symbols based on the decision variables calculated at the STBC decoding step. In this case, the decision variables are calculated using a linear equation that allows a squared Euclidean distance from OFDM reception symbols, which are demodulated during the B symbol periods, to have a local minimum for each decision variable when the STBC encoding and the frequency responses estimated during the B OFDM symbol periods are applied.
