Abstract

RECONSTRUÇÃO DE SÍMBOLO DE SINAL DE REFERÊNCIA ITERATIVA E ESTIMATIVA DE CANAL. Métodos, sistemas, e dispositivos para comunicações sem fio são descritos. Um dispositivo de transmissão (por exemplo, um equipamento de usuário (UE) ou estação base) pode reduzir uma razão de potência de pico para média (PAPR) recortando sinais transmitidos para um dispositivo de recepção de acordo com um nível de recorte. O dispositivo de recepção pode receber, a partir do dispositivo de transmissão, uma indicação do nível de recorte associado a um sinal de referência. O dispositivo de recepção pode receber o sinal de referência e identificar distorções com base no nível de recorte. O dispositivo de recepção pode reconstruir iterativamente os picos do sinal de referência recortado até que o dispositivo de recepção seja capaz de obter símbolos piloto precisos para uso na estimativa de canal. As técnicas aqui descritas podem permitir que os dispositivos de recepção melhorem a eficiência e a confiabilidade das comunicações melhorando a estimativa de canal, o que pode aumentar a probabilidade de decodificar com sucesso as informações transmitidas.
