The use of one directional antenna in MIMO systems utilizes the fact that faded propagation is not random in azimuth, but has local maxima. Thus it can improve the link performances (Throughput, Bit Error Rate and Signal to Noise), provided that the directional antenna can be rotated towards the optimal direction. Indoor tests with two antennas (one monopole and one microstrip) show typical capacity...
Two multicoupled multimode fibres can act either as an encoder or as its matched-filter decoder, depending on which terminals are used. Such a network which may find applications in communications and microwave systems has been demonstrated using fused T couplers, fibre connectors, and multimode optical-fibre delay lines.
