Item type:Publication, Access status: without files , A FPGA correlation receiver for CDMA encoded LiDAR signals(2017-07-10); ; ; We present a digital implementation of a correlation receiver for pulsed CDMA lidar signals in direct-time-of-flight systems. A coded time-of-flight lidar is capable to identify its own signals and to reject state-of-the-art uncoded or differently coded pulses. The required sampling rate of the system ADC is determined. For processing the digitized receive signal a correlation filter realized in FPGA hardware is presented. A single filter running at the maximum viable FPGA clock rate of 200 MHz does not ensure reliable signal detection. The filter was parallelized five times to allow processing of 1000 MSa/s signals. Simulations with experimental coded lidar data prove the system's code separation properties.Publicationtype: Conference Paper78
