摘要： A system and method for channel estimation in a wireless local area network. A corresponding channel estimation method includes the steps of: receiving a preamble message and despreading the preamble message into several symbol signals, each symbol signal containing several discrete signals; determining for each symbol signal a peak sign assignment; establishing several data windows for the symbol signals at the starting points of the discrete signals; multiplying the discrete value of each discrete signal of each data window by the corresponding peak sign assignment and accumulating the product in the first data frame; repeating the above steps for the next discrete signal and accumulating them in the second data frame, . . . , the Nth data frame; computing the accumulated value in the data frames and obtaining the data frame with the maximum value; estimating a channel signal from the previously determined data frame.

摘要： An apparatus of sequentially decoding CCK codes includes a series of received signal registers used to respectively temporarily save the received signals, a phase selector used to select one numeral from 1, −1, j or −j respectively for CCK code of each chip to multiple with the signal register, a series of adders used to sequentially complete adding operation, a series of sequential operation registers used to save values obtained from the sequential selecting operation of the phase selectors and the sequential adding operation of the adders, and a comparing device used to select a maximal value from those saved in the operation registers. The comparing device includes a comparator and a maximum register. According to the invention, the data processing speeds up while the hardware complexity is reduced.
