Channel Estimation and interference in Systems of Frequency Division Multiple Access single Carrier and multi Carrier

摘要

In a system of Frequency Division Multiple Access (sc-fdma) only Carrier, a receiver receives symbols transmitted from a transmitter, determines a set of subbands used by the transmitter, Transmission processes the received Symbols for the whole of Sub bands, ob Has received Pilot values for a Pilot transmitted,And obtains the values of received Data for the data transmitted. The receiver can carry out iteratively Estimating the channel and Interference for the transmitter.The receiver Selects an initial estimation of interference, derives a Channel estimate based on the received Pilot values and estimation of interference, and derives a New estimate of interference based on the received Pilot values and the estimation of the Channel.The receiver can repeat the derivation of the estimation of the channel and Interference Estimation for multiple iterations. Then the receiver performs Data Detection and / or receiver Spatial Processing on received Data values based on the estimation of the channel and Interference estimation.
