Sabe-se que os algoritmos MUSIC e ESPRIT podem estimar simultaneamente tanto a Direção de Chegada (DOA) instantânea quanto a Espalhamento Angular (AS) instantâneo em ambientes de espalhamento múltiplo. Esses algoritmos usam o Extended Array Mode Vector (EAMV) com ângulo complexo. O trabalho anterior avaliou o desempenho desses algoritmos comparando o DOA estimado e o AS estimado com o DOA e o AS dados no EAMV, que utiliza a aproximação de primeira ordem. Assim, este método de avaliação não refletiu claramente a precisão da estimativa do MUSIC e do ESPRIT. Este artigo apresenta o desempenho da estimativa conjunta de MUSIC e ESPRIT, introduzindo os critérios de avaliação. Para isso, a assinatura espacial (SS) é reconstruída a partir das estimativas do DOA e do AS, e comparada com a verdadeira SS no sentido do ajuste dos dados.

Abstract: It is known that MUSIC and ESPRIT algorithms can estimate simultaneously both the instantaneous Direction of Arrival (DOA) and the instantaneous Angular Spread (AS) in multiple scattering environments. These algorithms use the Extended Array Mode Vector (EAMV) with complex angle. The previous work evaluated the performance of those algorithms by comparing the estimated DOA and the estimated AS with the DOA and the AS given in the EAMV, which uses the first-order approximation. Thus, this evaluation method has not clearly reflected the estimation accuracy of MUSIC and ESPRIT. This paper presents the joint estimation performance of MUSIC and ESPRIT by introducing the criteria for evaluation. For this, the spatial signature (SS) is reconstructed from the estimates of the DOA and the AS, and compared to the true SS in the meaning of data fitting.
