A layered decoding architecture with a reduced number of hardware buffers for low-density parity-check (LDPC) decoding by storing a variable-to-check message. When a check node begins a new operation, a variable-to-check message (Q) is added to a check-to-variable message (R) obtained in previous check-node operation to obtain an updated APP value. Then, the R value for the check node in the layer being processed is deducted from the APP value to obtain a variable-to-check message (Q). This variable-to-check message is stored in the memory and inserted into the check node equation to obtain a check-to-variable message. Finally the check-to-variable message obtained in this operation is stored to the check-to-variable message shift register to complete the updating operation for the check node and the variable node for the layer being processed. Improved hardware utilization and fewer buffers, thus achieving a smaller hardware area while retaining the converge speed, is obtained.

The embodiment of the invention has the advantages that only one RFID antenna is used; the advantages of simple system structure, low cost, low deployment difficulty and high hardware utilization rate are realized.

The invention discloses a method for retransmitting enhanced self-adaptive data. The method adopting a self-adaptation technique is: when a communication channel is in good condition, to code data by means of a high bit rate coder which has a high transmission rate and few redundant error-correcting codes and to complete initial transmission of the data, or to use a method of information bit puncturing hybrid retransmission of data for improving the utilization rate of hardware and the system throughput and saving energy; and when the communication channel is in poor condition, to code data by means of a low bit rate coder which has a high transmission rate and more redundant error-correcting codes and to complete initial transmission of the data, or to use a method of parity bit puncturing hybrid retransmission of data for guaranteeing the reliability of communication transmission. The method of the invention has the combined advantages of technologies of information bit puncturing hybrid retransmission and parity bit puncturing hybrid retransmission, and thus can not only improve the utilization rate of the hardware, reduce the time delay for transmission processing, improve thesystem throughput and saves energy, but also ensure good error-correcting transmission performance in poor communication channel condition.
