Abstract  Abstract

Efficient retransmission of data using symbolic accumulation, which retransmits a badly received packet with a lower energy per bit simultaneously in the same frame as a new packet. The destination device receives the data transmission and retransmission, demodulates the signal, and separates the received data into new and retransmitted packets. The destination device then accumulates the energy of the retransmitted packet with the energy already accumulated for the wrongly received packet and decodes the accumulated packet. Accumulation of additional energy provided by subsequent retransmissions improves the possibility of accurate decoding. Since a wrongly received packet is retransmitted simultaneously with the transmission of a new data packet, the throughput can be improved. The capacity is maximized because retransmission of erroneously received packets is performed at lower energy than retransmission of new packets.
