| 发明名称 | Digital combiner for phased-array RF receivers | ||
| 摘要 | Methods and systems for receiving radio frequency (RF) signals include adjusting a digital baseband signal from a first RF front-end to compensate for errors based on a correlation value from a first Golay correlator. A set of digital baseband signals from a set of respective additional RF front-ends is adjusted to compensate for errors based on correlation values from a second Golay correlator. A digital baseband signal to be adjusted is selected on a time-sharing basis. The adjusted digital baseband signal from the first RF front-end and the adjusted set of digital baseband signals from the set of respective additional RF front-ends are combined. | ||

| 主权项 | 1. A method for receiving radio frequency (RF) signals, comprising: adjusting a digital baseband signal from a first RF front-end to compensate for errors based on a correlation value from a first Golay correlator; adjusting a plurality of digital baseband signals from a plurality of respective additional RF front-ends to compensate for errors based on correlation values from a second Golay correlator, wherein a digital baseband signal to be adjusted is selected on a time-sharing basis; and combining the adjusted digital baseband signal from the first RF front-end and the adjusted plurality of digital baseband signals from the plurality of respective additional RF front-ends. | ||
