This report deals with the LTE downlink transmission scheme, from the base station to the terminal (the mobile phone), which is based on multicarrier modulation: OFDM (Orthogonal Frequency Division Multiplexing). LTE also supports the use of multiple antennas at both the base station and the terminal to improve communication performance: Multiple Input -- Multiple Output (MIMO) antenna processing.The project focuses on the different methods for estimating the time-varying channel between the transmitter and the receiver: to carry out coherent demodulation, the mobile terminal requires estimates of the downlink channel, and to allow this, known symbols are inserted in the transmitted signal.
