Adaptive Pilot Distribution for OFDM Systems in Time-Variant Channels
Original language description
OFDM is sensitive to frequency offsets and phase noise. In order to estimate the channel, training symbols (pilots) are inserted among the transmitted data. The pilot spacing in time and frequency must be designed according to the coherence time and coherence bandwidth of the channel. In this paper an adaptive method for pilot distribution according to the variation level of the channel is described. It is shown that the adaptive method increases the total capacity of the system.
