| description | According to the problems of the existing timing recovery algorithm with the time-domain orthogonal frequency division multiplexing (TDS-OFDM) modulation in the wireless multimedia transmissions of 5G communications,such as slow processing speed and big theoretical distance,a parallel MAP timing recovery algorithm was proposed.Specifically,the Lagrangian interpolation was used and the amplitude and polarity change of the optimal sampling points were extracted to detect the timing error efficiently.Meanwhile,with the parallel maximum a posteriori (MAP) criterion,the timing error estimate was obtained at high speed.The simulation results show that the accuracy of the proposed algorithm is improved,when comparing with the existing MM algorithm,Gardner algorithm and others.The estimation result is very close to the MAP timing recovery algorithm,the difference is about 2 dB. |
