Research of the methods of an equalizing with using OFDM signals for communication systems

摘要

The article discusses recommendations about a choice of the valuation method of transfer function of the radio propagation channel by using pilot subcarriers. Thedistances between pilot subcarriers in case of which the high data transmission rate will remain for standard models of the channel propagation are selected. Process of an estimation of transfer function of the radio propagation channel by using pilot subcarriers is modeled. Bit error rate for each of the offered methods is estimated.
