摘要：
A method of signal processing, or corresponding apparatus, includes providing multiple analog receive signals at respective antennas and selecting one antenna at a time in an iterative manner, to cycle through the antennas and provide a multiplexed analog signal. The multiplexed analog signal is filtered at a filter to pass a predetermined frequency band. The multiplexed analog signal is sampled at a single analog to digital converter to generate a multiplexed digital signal. The multiplexed digital signal is demultiplexed to generate multiple digital signals for digital processing. Sharing a receiver and ADC among multiple antennas results in reduced cost and power. Such cost and power reductions in turn enable larger antenna arrays than are available with prior art techniques, thereby promoting increased throughput and coverage.
摘要（中）：
一种信号处理方法或相应装置，包括在各个天线处提供多个模拟接收信号，并以迭代方式一次选择一个天线，以循环穿过天线并提供复用的模拟信号。 复用的模拟信号在滤波器处被滤波以通过预定的频带。 复用的模拟信号在单个模数转换器处采样以产生多路复用的数字信号。 复用的数字信号被解复用以产生用于数字处理的多个数字信号。 在多个天线之间共享接收机和ADC会降低成本和功耗。 这样的成本和功率减少又使得能够比现有技术可用的更大的天线阵列，从而促进增加的吞吐量和覆盖。
