Abstract

APARELHO DE SUPRESSãO DE POTêNCIA DE CRISTA E MéTODO DE SUPRESSãO DE POTêNCIA DE CRISTA A presente invenção refere-se a um aparelho de supressão de potência de crista que é capaz de aperfeiçoar a característica de taxa de erro de recepção de um aparelho em um lado de recepção. Neste aparelho, uma parte de limitação (102) limita um sinal de entrada, assim, suprimindo a potência de crista do sinal. Um circuito de subtração (104) extrai um componente de distorção dentro da faixa do sinal suprimido de potência de crista.Um circuito de subtração (111) subtrai o componente de distorção dentro da faixa extraída do sinal suprimido de potência de crista, assim, removendo um componente de distorção residual na faixa do sinal suprimido de potência de crista.
