Wireless mesh network and method of relaying signal in wireless mesh network

A method of relaying a signal in a wireless mesh network of nodes, the method comprising:

• receiving, at a first node comprised in the network, 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;
• generating and transmitting, at the first node, a second signal, the second signal corresponding to the first signal;
• wherein 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;
• wherein a time offset r between the start titne 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;
• and
• wherein the time offset r is chosen such that any pair of corresponding signals has a time offset q which is less than s from the perspective of any relay node in the network.
