Channel Estimation and Interpolation for Fourth Generation Mobile Broadband Telecommunications
نویسندگان
چکیده
This paper studies the problem of channel estimation for the downlink in broadband LTE communications. A Kalman Filter is used to combine channel soundings made with pilot tones that are deployed at different times and in different frequency bands on a pre-selected pattern. This Kalman filter is presented in a form directly suitable for implementation as a periodically time varying filter, in the case where periodic pilot tone data is available. Simulation results illustrate the efficacy of this approach.

Data-derived iterative channel estimation with channel tracking for a mobile fourth generation wide area OFDM system
In this paper an iterative channel estimation technique for a mobile fourth generation coherent Orthogonal Frequency Division Multiplexing (OFDM) system is proposed. Coherent detection dictates that a per-subband estimate of the frequency response of the channel is generated for each OFDM symbol. This is often achieved by inserting pilot symbols amongst the data symbols in the OFDM modulation g...
