Channel estimating method and channel estimator in OFDM communication system

摘要

in the channel estimation method in an orthogonal frequency division multiplex communication system and a channel estimator are provided. The channel estimation method in an OFDM communication system according to the present invention, placing the pilots included in the received symbol (symbol) in the first area of the memory for the channel estimate and the second located between the first region After estimating the data in the area, and the data estimating comprises the step of placing the pilots of each symbol are sequentially received in the first region, and update the estimated data of the second area. Preferably, the memory may have a size corresponding to one symbol. Channel estimation method and channel estimator in the OFDM communication system according to the invention has the advantage to minimize the amount of memory used for channel estimation by carrying out a single symbol basis, while still increasing the speed of channel estimation channel estimates .
