| 发明名称 | Multi-antenna receiver with a time synchronization common to the different receiver chains | ||
| 摘要 | The invention relates to a receiver of a signal built as successive frames, comprising a plurality of antennas, a signal receiving chain associated with each antenna, and a power amplifier on each receiving chain to which is applied a gain set point provided by a gain control unit characterized in that it comprises an antenna selecting unit configured to select one antenna from the plurality of antennas, and a time synchronizing unit configured to determine the frame start and end times in the signal received by the selected antenna. The antenna selecting unit is further configured to assess the gain set point of each receiving chain and to eliminate from the selection each antenna associated to a receiving chain which gain set point in not in a steady state. | ||

| 主权项 | 1. A receiver of a signal built as successive frames, comprising a plurality of antennas, a signal receiving chain associated with each antenna, a power amplifier on each receiving chain to which is applied a gain set point provided by a gain control unit, an antenna selecting unit configured to select one antenna from the plurality of antennas, and a time synchronizing unit configured to determine the frame start and end times in the signal received by the selected antenna, wherein the antenna selecting unit is further configured to assess the gain set point of each receiving chain and to eliminate from the selection each antenna associated to a receiving chain which gain set point is not in a steady state, wherein each receiving chain further comprises a Fourier transform unit with a sequencing controlled by the time synchronizing unit. | ||
