| Abstract [eng] |
Case is when two reflections are in close proximity is analysed. Such proximity introduces bias errors in ToF estimators for all interfering signals. Purpose of the investigation was the comparison of the time and frequency domain estimation algorithms with the aim to establish the insight into possible algorithms which are capable to reduce those errors. Evaluation is based on simulation using the pre-recorded real single reflection. Simulation is supported by additional experimental results. |
