摘要
En 中文
A novel implicit transmission with bit flipping (ITBF) technique is introduced to transmit a coded stream implicitly while transmitting a coded stream explicitly over a channel. ITBF flips a set of chosen parity bits of the explicitly transmitted stream according to an implicit stream. Numerical results obtained using the low density parity check (LDPC) code employed in the 5G standard show that ITBF can transmit an implicit stream up to 13.19% of the rate of transmission of the explicit stream without significantly sacrificing performance, or increasing the decoding complexity or the decoding delay. The ITBF is combined with collection of punctured code decoding (CPCD) to form implicit transmission with collection decoding (ITCD) schemes that can further increase the rate of transmission on the implicit stream without increasing the decoding delay, however, with a slight increase in the decoding complexity. It is demonstrated with the LDPC code in the WiFi standard that ITCD can transmit an implicit stream at up to 25% of the rate of transmission of the explicit stream.
