Data transfer method involves allocating coded data to bit positions depending on whether corresponding data packet is being transmitted for first time or is a repeat

摘要

The method involves encoding data packets, allocating coded data to bit positions in modulation symbols, sending symbols over a communications path, receiving/demodulating symbols in a receiving station, decoding packets, confirming received packets to sending station and repeated transmission of an unacknowledged packet. Allocation of coded data to bit positions is conducted depending on whether the packet is being transmitted for the first time. The method involves forming data into packets, encoding the packets in a transmission station, allocating the coded data to bit positions in modulation symbols, transmitting the symbols over a communications path, receiving and demodulating the symbols in a receiving station, decoding the packets, confirming or otherwise the received packets to the sending station and repeated transmission of an unacknowledged packet with transmission parameters that can be different. The allocation of coded data to bit positions is conducted depending on whether the corresponding packet is being transmitted for the first time or is a repeat.
