On Geostatistical Methods for Radio Environment Maps Generation under Location Uncertainty

Abstract: Radio environment map (REM) can provide important information for designing and optimizing the performance of wireless communication networks. However, the location uncertainty related to the measurements used to build the REM can considerably deteriorate the accuracy of such map. This paper addresses this problem by proposing a modified approach of a classical geostatistical prediction tool, named Kriging method, which incorporates the location uncertainty and is able to improve the REM accuracy without addin… Show more

“…The second step is the spatial prediction. Given the measurements, the model-based basis functions, and the covariance matrix from the previous step we use the location of interest to solve the universal kriging and obtain the kriging weights ( 26), (27). Finally, we predict the SNR at the location of interest and corresponding SNR variance (28).…”

“…Diversos artigos tratando do uso de REM gerados a partir de técnicas de geo-estatística podem ser encontrados na literatura. Dentre os mais relacionados ao presente trabalho, podemos citar as referências [6], [7], [8]. Em [6] os autores estudam o uso dos mapas REM na estimativa da qualidade de uma rede celular, com foco no problema da incerteza das posições de amostragem de potência recebida.…”

“…Dentre os mais relacionados ao presente trabalho, podemos citar as referências [6], [7], [8]. Em [6] os autores estudam o uso dos mapas REM na estimativa da qualidade de uma rede celular, com foco no problema da incerteza das posições de amostragem de potência recebida. Note-se que no presente trabalho assume-se que as posições onde as amostras de potência de recepção foram coletadas são conhecidas sem erros.…”
