Estimating the Preamble and Carrier Offset in Asymmetric Channel for Synchronization in Broadband Signal Processing

Awinash Kumar, Arvinder Pal Singh Kalsi

In multipath fading the signal is transmitted through free space channel which has its significance characteristics in the time and frequency domain. At the receiver side we need a perfect synchronization model so that we can achieve better spectral efficiency and BER. More over Synchronization will vary according to the channel; traffic pattern and the path loss component of the different environment like urban; sub urban etc. A dynamic receiver should successfully receive and demodulate data with effective BER analysis. In which Timing synchronization is used to determine the arrival of data burst and the symbol boundaries whereas frequency synchronization is used to synchronize local oscillator to a carrier frequency. But in multipath the synchronization is very difficult. In this research paper; A transceiver model has been simulated using Matlab and performance evaluation has been done for uplink and downlink transmission with the effect of different environment includes AWGN channel; multipath channel; and SUI channel model. In this paper Multicarrier modulation OFDM has been used for broadband wireless environment with its standard FFT size. In second stage; simulations are done for synchronization considering with preamble; the carrier frequency offset and phase noise is estimated at the receiver. With our analysis frequency selective fading environment increases the robustness to narrowband interference and offers high spectra with equalization strategies.
