| Abstract: | With the combination of the antenna arrays and signal processing, the position of a Radio Frequency Identification(RFID) tag can be estimated. This can be done by applying different types of Direction Of Arrival (DOA) estimating algorithms. This paper studies the effect of the single-bit quantization on the DOA estimation of two sources. Previous research has addressed ways to reconstruct covariance matrices and the effect of single-bit quantitation for a single source, this study focuses on estimating the DOA of two sources by applying two types of algorithms, which are Classical Beamforming and Multiple Signal Classification (MUSIC). The comparison of these two algorithms revealed that Classical Beamforming showed robust performance for both the original signals and quantized signals once the SNR reached -10[dB]. In contrast, MUSIC had an unexpected degradation of accuracy with SNR higher than 10[dB]. With this analysis, further research is still required to overcome the degradation of the accuracy when MUSIC is applied to the quantized signal with high SNR. |
