Abstract

DETECÇÃO DE LINHA DE VISÃO BASEADA EM REDE NEURAL PARA POSICIONAMENTO. São fornecidas técnicas para o posicionamento baseado em rede neural de um dispositivo móvel. Um método de exemplo para determinar um atraso de linha de visão, um ângulo de chegada, ou um valor de ângulo de partida, de acordo com a divulgação, inclui receber informações de sinal de referência, determinar uma resposta de frequência de canal ou uma resposta de impulso de canal com base nas informações de sinal de referência, processar a resposta de frequência de canal ou a resposta de impulso de canal com uma rede neural, e determinar o atraso de linha de visão, o ângulo de chegada, ou o valor de ângulo de partida com base em uma saída da rede neural.
