A técnica de pré-codificação híbrida (HP) tem sido amplamente considerada como uma abordagem promissora para sistemas de comunicação por ondas milimétricas. Em geral, a estrutura HP existente com uma complicada rede de deslocamento de fase de alta resolução pode atingir uma eficiência espectral quase ideal, no entanto, envolve alto consumo de energia. A arquitetura HP com uma rede de switches com eficiência energética pode reduzir significativamente o consumo de energia. Para alcançar a máxima eficiência energética, este artigo se concentra na arquitetura HP com rede de switch e considera uma nova estrutura HP de rede analógica adaptativa para tais sistemas MIMO mmWave, que pode fornecer ganhos potenciais de array. Além disso, um algoritmo de atualização de coordenadas adaptativo multiusuário é proposto para o problema de projeto HP desta nova estrutura. Os resultados da simulação verificam que o projeto proposto pode alcançar melhor eficiência energética do que outros esquemas de HP propostos recentemente quando o número de usuários é pequeno.

Abstract: The hybrid precoding (HP) technique has been widely considered as a promising approach for millimeter wave communication systems. In general, the existing HP structure with a complicated high-resolution phase shifter network can achieve near-optimal spectral efficiency, however, it involves high energy consumption. The HP architecture with an energy-efficient switch network can significantly reduce the energy consumption. To achieve maximum energy efficiency, this paper focuses on the HP architecture with switch network and considers a novel adaptive analog network HP structure for such mmWave MIMO systems, which can provide potential array gains. Moreover, a multiuser adaptive coordinate update algorithm is proposed for the HP design problem of this new structure. Simulation results verify that our proposed design can achieve better energy efficiency than other recently proposed HP schemes when the number of users is small.

AB - The hybrid precoding (HP) technique has been widely considered as a promising approach for millimeter wave communication systems. In general, the existing HP structure with a complicated high-resolution phase shifter network can achieve near-optimal spectral efficiency, however, it involves high energy consumption. The HP architecture with an energy-efficient switch network can significantly reduce the energy consumption. To achieve maximum energy efficiency, this paper focuses on the HP architecture with switch network and considers a novel adaptive analog network HP structure for such mmWave MIMO systems, which can provide potential array gains. Moreover, a multiuser adaptive coordinate update algorithm is proposed for the HP design problem of this new structure. Simulation results verify that our proposed design can achieve better energy efficiency than other recently proposed HP schemes when the number of users is small.
