A comunicação de retroespalhamento é uma tecnologia emergente de acesso sem fio para realizar terminais de potência ultrabaixa que exploram a reflexão modulada de ondas de rádio incidentes. Este artigo propõe um método para medir o ângulo de fase do link de retroespalhamento usando análise de componentes principais (PCA). A medição do ângulo de fase do link de retroespalhamento no receptor é essencial para maximizar a qualidade do sinal para posterior desmodulação e para medir a distância e o ângulo de chegada. A desvantagem da medição popular do ângulo de fase com média de fase ingênua e análise de regressão linear é produzir ângulo de fase errôneo, onde o ângulo de fase é próximo de $pm rac{pi}{2}$ radiano e a qualidade do sinal é ruim. A vantagem da proposta é quantificada com uma simulação computacional, um experimento conduzido e experimentos de propagação de rádio.

Abstract: Backscatter communication is an emerging wireless access technology to realize ultra-low power terminals exploiting the modulated reflection of incident radio wave. This paper proposes a method to measure the phase angle of backscatter link using principal component analysis (PCA). The phase angle measurement of backscatter link at the receiver is essential to maximize the signal quality for subsequent demodulation and to measure the distance and the angle of arrival. The drawback of popular phase angle measurement with naive phase averaging and linear regression analysis is to produce erroneous phase angle, where the phase angle is close to $pmrac{pi}{2}$ radian and the signal quality is poor. The advantage of the proposal is quantified with a computer simulation, a conducted experiment and radio propagation experiments.
