Doppler Spread Estimation for Broadband Wireless OFDM Systems Over Rician Fading Channels
In this paper, we present a new Doppler spread estimation algorithm for broadband wireless orthogonal frequency division multiplexing (OFDM) systems with fast time-varying and frequency-selective Rayleigh or Rician fading channels. The new algorithm is developed by analyzing the statistical properties of the power of the received OFDM signal in the time domain, thus it is not affected by the in...

متن کاملTurbo Trellis Coded Modulation on Partially Coherent Fading Channels
| In this paper, we design parallel concatenated convolutional codes (PCCCs) for trellis coded modulation (TCM) over the following discrete two-dimensional (2D) channels: (a) a slow-fading Rayleigh channel with discrete carrier tracking by a phase locked loop (PLL), where the PLL signal-to-noise ratio (SNR) is proportional to the fading amplitude squared; (b) an additive white Gaussian noise (A...
