Beam steering algorithm for NLOS wireless systems with predefined parameters

摘要

The present invention relates to the fields of link adaption, multi-path communication, non-line of sight wireless communication. The present invention especially relates to a communication system, a communication device and a communication method. The problem to be solved by the present invention is to reduce the time which is necessary for the adaption to a specific communication path in a communication system. The method of communication between a first communication device and a second communication device based on a plurality of communication paths comprises a step of transmitting (S10, S12, S9) a signal on a number of communication paths, a step of determining and storing (S14B) at least one link parameter for each one of said number of communication paths based on a signal transmitted on the respective communication path and, when switching to a communication path in order to operate a communication link, a step of operating (S6) a communication link on said communication path based on at least one stored link parameter of said communication path. The method may comprise a step of selecting (S4) said communication path on which said communication link is operated based on one or more of said signals transmitted on said number of communication paths. Said first communication device (1) and/or said second communication device (2) may comprise a narrow beam antenna (11, 12) which is adapted to be steered to different positions corresponding to different communication paths.
