摘要： Low density parity check (LDPC) decoders are described utilizing a sequential schedule called Zigzag LBP (Z-LBP), for a layered belief propagation (LBP) architecture. Z-LBP has a lower computational complexity per iteration than variable-node-centric LBP (V-LBP), while being simpler than flooding and check-node-centric LBP (C-LBP). For QC-LDPC codes where the sub-matrices can have at most one “1” per column and one “1” per row, Z-LBP can perform partially-parallel decoding with the same performance as C-LBP. The decoder comprises a control circuit and memory coupled to a parity check matrix. Message passage is performed within Z-LBP in a first direction on odd iterations, and in a second direction on even iterations. As a result, a smaller parity check matrix can be utilized, while convergence can be more readily attained. The inventive method and apparatus can also be implemented for partially-parallel architectures.

摘要： The present invention relates to a method of wirelessly transmitting and receiving audio digital signals of the type having a first plurality of blocks with each block having a second plurality of frames, with each frame having a third plurality of subframes, with each subframe having a preamble and a binary data. The method efficiently transmits and recomposes the digital audio signals by searching for the preamble associated with a subframe, which is the first subframe of a frame, with the frame being the first frame of a block, and then transmitting wirelessly only the binary data of each subframe, in each frame, in each block thereafter. In a preferred embodiment, the protocol for the transmission of data calls for each data packet that is transmitted to consist of 512 bytes. The data packet transmitted by the transmitter must be acknowledged by the transmission of an acknowledgement (ACK) packet from the receiver. In the event, the data packet is not received and/or the ACK packet is not received, and transmission must recommence, synchronization is accomplished by the retransmission of data packet immediately after the preamble of the first subframe of the first frame of a block.

Each of the periodic coupling structures is positioned parallel to adjacent periodic coupling structures with a separation distance between each periodic coupling structure being within one wavelength of the radio frequency signal. The periodic near field directors may include first and second periodic near field directors that are coupled to each other for transmitting and receiving the radio frequency signals between the first and second periodic near field directors, wherein there is an air gap between the first and second periodic near field directors.
