Linearly Time-Varying Channel Estimation and Symbol Detection for OFDMA Uplink Using Superimposed Training
We address the problem of superimposed trainings- (STs-) based linearly time-varying (LTV) channel estimation and symbol detection for orthogonal frequency-division multiplexing access (OFDMA) systems at the uplink receiver. The LTV channel coefficients are modeled by truncated discrete Fourier base...
