Channel estimation method for OFDM in low SNR based on two-dimensional spreading
Original language description
In this paper, we present a channel estimation method based on two-dimensional signal spreading applicable to Orthogonal Frequency Multi- ple Access (OFDM) multicarrier systems. Our method exploits a spreading of a transmitted data signal as well as a pilot signal over the assigned fre- quency range and time period. As a spreading sequence we exploited orthog- onal Walsh-Hadamard sequences. When compared with traditional pilot symbol based channel estimation, our method is beneficial in low Signal to Noise Ratio (SNR). For a comparison of our method with state-of-the-art channel estimation method, we utilized an open source LTE downlink simulator developed at TU Vienna. This enables a reproducibility of our results. Considering the LTE system, our method outperforms the traditional approach in typical range of SNR from -5 dB to 10 dB. For a comparison of a throughput performance, a number of channel models has been employed.
