Abstract
A multi-input multi-output (MIMO) radar system and method of performing low-latency decoding in a MIMO radar system. The method includes transmitting a different linear frequency-modulated continuous wave (LFM-CW) transmit signal from each of N transmit elements of the MIMO radar system, each transmit signal associated with teach of the N transmit elements including a respective code, and receiving reflections associated with each of the transmit signals from each of the N transmit elements at each receive element of the MIMO radar system. Processing each symbol corresponding with each received reflection on a symbol-by-symbol basis is done to obtain a respective decoded signal prior to receiving all the received reflections associated with all the N transmit elements, wherein the processing includes using a Hadamard matrix with N columns in which each column is associated with the respective code transmitted by each of the N transmit elements.
