Abstract

resumo “circuito de compensação de distorção e dispositivo de transmissão usando circuito de compensação de distorção e amplificador de potência de alta frequência” o propósito da invenção é reduzir o retardo de transmissão de laço cartesiano para compensar a distorção que ocorre em um amplificador de potência de alta frequência e faz a compensação de distorção convergir rapidamente, aumentando, desse modo, a eficiência. um dispositivo de transmissão tem: um amplificador de potência de alta frequência; um circuito de compensação de pré-distorção para gerar independentemente os coeficientes do sinal de compensação de distorção para cada ordem das distorções simétricas pares e ímpares do amplificador de potência de alta frequência; um meio para variar a tensão de fonte de alimentação do amplificador de potência de alta frequência com um sinal de entrada ofdm de modulação ortogonal; um conversos de frequência digital; uma faixa de alta frequência adc e uma faixa de alta frequência dac. no dispositivo de transmissão, um sinal de compensação de distorção de erro é criado a partir da saída do amplificador de potência de alta frequência e o sinal de entrada ofdm de modulação ortogonal e um dispositivo de retardo é inserido no estágio anterior de um circuito de compensação de distorção, em que o dito dispositivo de retardo tem um retardo equivalente a uma constante de tempo para variar a tensão de fonte de alimentação do amplificador de potência de alta frequência com o sinal de entrada ofdm de modulação ortogonal.
