WIRELESS MESH NETWORK AND METHOD OF RELAYING SIGNAL IN WIRELESS MESH NETWORK

摘要

A wireless mesh network of nodes is disclosed. The network comprises at least one relay node, the at least one relay node being configured to receive a first signal, the first signal corresponding to a first symbol comprised in a data frame, the first symbol having a first symbol duration s; and to generate and transmit a second signal, the second signal corresponding to the first signal. The first signal and the second signal are modulated such that a sum of the first signal and the second signal is capable of being received and demodulated by at least one relay node so as to obtain a sum of symbols including the first symbol and the second symbol. A time offset r between the start time of the transmission of the second signal by the relay node and the time at which the first signal was received by the relay node is smaller than the first symbol duration s. The time offset r is chosen such that any pair of corresponding signals has a time offset of less than s from the perspective of any relay node in the network.
