# BEM-Based Channel Estimation and Interpolation Methods for Doubly-Selective OFDM Channel Abstract: In high-speed environments, the time and frequency selective (doubly-selective) channel which introduces the inter-carrier interference (ICI) into OFDM system is a big challenge for receiver design.

Application background. Communication system time-varying channel system modeling, kinds and Simulation of the BEM model and the model of LTV, use relay fading channels, such channel modeling can be applied to OFDM systems and MIMO system, can also be extended to the MIMO system in a large scale

Simulate the transmission and reception of BPSK data over an AWGN channel by using turbo encoding and decoding. Specify simulation parameters, and then compute the effective coding rate and noise variance. For BPSK modulation, equals because the number of bits per symbol (bps) is 1.

The least squares estimates of the channel frequency response at the pilot symbols are calculated as described in On Channel Estimation in OFDM Systems [2] . Feb 20, 2020 channel estimation, under different notions of sparsity in the channel model.

The OFDM channel in the high-speed train environment is modeled by using basis expansion model (BEM). The estimation problem of the channel impulse response and Doppler frequency offset are studied. In the simulation, the modeling performances of There are set of complementary sequences known as Golay sequences that are used for channel estimation because of the =2.7 ns$. And assume we have Additive White Gaussian noise.

### The following Matlab project contains the source code and Matlab examples used for blind channel estimation for mimo systems using linear space time codes. The channel estimation algorithm is based on a subspace approach.

Through interpolation, it is possible to estimate the channel across an arbitrary number of subframes. This page of MATLAB source code covers channel estimation and channel equalization for OFDM based system. Transmitted packet after passing through the wireless channel or environment will get impaired or corrupted due various impairments over the path. This leads to poor bit error rate of the wireless system. Perform channel estimation for general STBC-MIMO systems using a subspace approach.
