| 摘要 | Array amplitude modulation which includes mapping a data symbol to a phase modulation signal and an amplitude modulation signal for transmission from antenna elements; applying the phase modulation signal to the antenna element amplifiers; and generating a pattern of enabling/disabling the antenna element amplifiers as a function of the amplitude modulation to produce a phase and amplitude modulated transmission from the antenna elements. | ||

| 主权项 | 1. An array amplitude modulation system comprising: a mapping circuit for mapping a data symbol to a phase modulation signal and an amplitude modulation signal; a plurality of antenna elements; an amplifier associated with each antenna element, each amplifier having fixed amplification; and a control circuit responsive to said amplitude modulation signal to selectively enable/disable said amplifiers to produce a phase and amplitude modulation transmission from said antenna elements, the selectively enabling/disabling respectively turning on/off said amplifiers. | ||
