Abstract

A comparison of different lengths of maximum length sequences for channel sounding application is given. The results are obtained from simulations in LabView and Matlab in different channel models. A channel impulse response is extracted from simulated data for different pseudo noise sequence lengths and different channel models. Simulations are performed in LabView on sliding correlator channel sounder simulation model with data processing done in Matlab. Different power delay profiles with different spectrum statistics are used in simulations. RMS delay spreads are calculated and compared against sequence lengths. Additional tests are performed using USRP software defined radio (SDR) transceiver chain to obtain real life data.
