Wideband Channel Sounding Simulation Tool and Sounding Sequences Evaluation

This work presents the Base-Band Sounding Tool (BSOT), a wideband channel sounding simulator with different scenarios and configurations, providing the channels characterization in terms of delay and Doppler spreading. BSOT follows COST 207 statistical channel model and the pulse compression technique with direct cross-correlation at the receiver. Besides its validation results, the paper presentes a performance evaluation of 6 types of sounding sequences (Random, Kasami, Gold, m-Sequence, Zadoff-Chu and Golay), including a robustness evaluation with different lengths, sampling rates, and SNR values. The simulated outputs are coherent with the theoretical modeling, and the investigation of sounding sequences reveals a better sounding performance obtained with the Zadoff-Chu and Golay sequences.
