| 发明名称 | Amplitude enhanced frequency modulation | ||
| 摘要 | Methods and systems for transmitting a spectrally efficient signal. The method includes frequency modulating an input signal in a transmitter to generate a first frequency modulated (FM) signal and generating in the transmitter an amplitude modulated (AM) component based at least on the input signal. The method may then include generating a second FM signal based at least on the AM component and the first FM signal and sending the second FM signal to a receiver. | ||

| 主权项 | 1. A communication system comprising: a transmitter, comprising: a frequency modulator configured to generate a first frequency modulated (FM) signal based at least on an input signal;a component configured to generate an amplitude modulated (AM) component based at least on the input signal; andan amplitude modulator configured to add the AM component to the first FM signal thereby generating a second FM signal; wherein the transmitter is configured to send the second FM signal to a receiver. | ||
