Abstract
a divulgação fornece sistemas e métodos para redução de interferência em comunicações sem fio. o método pode incluir a recepção de um sinal composto com múltiplos sinais constituintes sobrepostos e um nível de ruído. o nível de ruído pode ter pelo menos um sinal de interferência coerente. o sistema pode caracterizar e sintetizar os múltiplos sinais constituintes sobrepostos sem conhecimento prévio. o método pode incluir receber uma entrada secundária compreendendo o pelo menos um sinal de interferência coerente. o método pode incluir o cancelamento do sinal de interferência coerente a partir do nível de ruído. o método pode incluir a emissão do primeiro sinal e o segundo sinal com um nível de ruído reduzido.
