Communication method and apparatus in a point-to-multipoint communication network

A node of a point-to-multipoint network, comprising:

• a receiver configured to:
• receive a transmission frame comprising a header including a repetition information and a data section comprising multiple modulation symbols, the repetition information specifying whether repetition of modulation symbols in the transmission frame occurs and if so an amount of repetition, the data section including at least two repeated modulation symbols in the frame that are repeated in accordance with the repetition information to represent a first modulation symbol;
• and a data recovery stage coupled to the receiver and configured to:
• extract the repetition information of the header;
• quantify the amplitude of each modulation symbol of the at least two repeated modulation symbols;
• and combine the amplitudes of the at least two repeated modulation symbols, based on the repetition information, to reconstruct the first modulation symbol represented by the at least two repeated modulation symbols;
• perform data recovery on at least a segment of the digital signal during each cycle of the point-to-multipoint network;
• and perform addition of amplitudes of repetitive symbols received in the downstream signal that are modulated with the repetition information.
