摘要： Embodiments of methods and means for passively emulating channels in a multiple-input multiple output (MIMO) system are provided. Such embodiments include passively splitting a plurality of radio frequency signals into a greater plurality of such signals. Each of the greater plurality of radio frequency signals can then be selectively and passively attenuated, delayed and/or phase shifted. The resulting modified radio frequency signals are then recombined crossed over channels and coupled to a plurality of output nodes. Economical and versatile device and system testing is thus facilitated in a low-noise radio frequency environment without the need for complex up/down frequency or analog/digital conversions.
摘要翻译：提供了在多输入多输出（MIMO）系统中被动地仿真信道的方法和装置的实施例。这样的实施例包括将多个射频信号被动地分割成更多个这样的信号。然后可以选择性地和被动地衰减，延迟和/或相移多个多个射频信号中的每一个。所得到的经修改的射频信号然后在通道上重新交叉并耦合到多个输出节点。因此，在低噪声射频环境中便利了经济且通用的设备和系统测试，而无需复杂的上/下频率或模拟/数字转换。

摘要： Embodiments of the present invention provide for adaptive cyclic delay diversity to be used in wireless transmissions to mobile devices. The cyclic delay diversity may be adapted through cyclic delay parameters determined based at least in part on a determined speed of the mobile device. Other embodiments may be described and claimed.

摘要： An improved digital mixer provides means for correcting a conventional mixer output that uses the full range of a mixer control variable to satisfy desired mixer constraints. The correction is accomplished by combining the mix output with a correction signal to satisfy the equationMIX=[A*K+B*/K]+[A*K+B*(/K)]/(2 n)+D.
