    • Exploiting the substantive reciprocity of internode channel responses through dynamic, adaptive modification of receive and transmit weights, enables locally enabled global optimization of a multipoint, wireless electromagnetic communications network of communication nodes. Each diversity-channel-capable node uses computationally efficient exploitation of pilot tone data and diversity-adaptive signal processing of the weightings and the signal to further convey optimization and channel information which promote local and thereby network-global efficiency. The preferred embodiment performs complex digital signal manipulation that includes a linear combining and linear distribution of the transmit and receive weights, the generation of piloting signals containing origination and destination node information, as well as interference-avoiding pseudorandom delay timing, and both symbol and multitone encoding, to gain the benefit of substantive orthogonality at the physical level without requiring actual substantive orthogonality at the physical level.
    • 通过对接收和发送权重的动态,自适应修改来利用节间信道响应的实质互惠,实现通信节点的多点无线电磁通信网络的本地启用的全局优化。 每个具有分集通道能力的节点都使用计算上有效的利用导频音数据和加权和信号的分集自适应信号处理来进一步传送优化和信道信息,从而提高局部性,从而提高网络全局效率。 优选实施例执行复杂的数字信号操作,其包括发送和接收权重的线性组合和线性分布,产生包含发起和目的地节点信息的导频信号以及干扰避免伪随机延迟定时,以及符号和多音 编码,以在物理层面获得实质正交性的好处,而不需要在物理层面上实际的实质正交性。
