摘要： A network controller receives data substantially simultaneously from multiple client nodes. The network controller assigns to each client node one or more sub-carriers of an orthogonal frequency-division multiplexing access frequency spectrum. The client nodes transmit substantially simultaneously M LDPC codewords that are encoded in a parity check matrix so that the number of rows m′ depend on the code rate and are mapped on its assigned sub-carriers. The network controller computes a bit log-likelihood ratio for each received bit of the codewords and arranges the bit LLR by codeword to align with an equivalent parity check matrix. The network controller decodes the codewords with the equivalent parity check matrix.

摘要： According to some embodiments of the disclosed method and apparatus, systems and methods are provided that utilize extra payload capacity present in a symbol pad of a PHY payload to decrease the coding rate of an FEC coding scheme without increasing the symbol rate or decreasing the PHY rate of a corresponding data transmission. If a symbol pad length that would result from encoding a MAC frame using a default coding scheme would be at least as great as a parity length of the default coding scheme, and a new coding scheme maintaining the same parity length but having a reduced information bit length may be determined and used to encode the MAC frame. Owing the reduced information bit length, the new coding scheme has a reduced coding rate, but maintains the same number of OFDM symbols as the default coding scheme.

摘要： Various systems and methods are provided for channel estimation. These systems and methods (a) determine a coherence bandwidth for the channel, (b) adapt the channel estimation based on the coherence bandwidth, and (c) perform channel estimation by transmitting a channel estimation symbol over a channel. In some embodiments, the channel estimation is adapted based on the coherence bandwidth. This may include selecting a number of channel estimation symbols to transmit in a packet. Additionally, the number of channel estimation symbols transmitted in a packet can be selected by increasing the number of channel estimation symbols when the coherence bandwidth of the channel is high or decreasing the number of channel estimation symbols when the coherence bandwidth of the channel is low.

摘要： Systems and methods are provided that allow multiple transmitting network devices to transmit under an orthogonal frequency divisional multiple access (OFDMA) mode to a receiving network device. The multiple transmitting network devices may be configured to perform constellation scrambling on the symbols they will be transmitting using a predetermined scrambling sequence. They may be further configured to synchronize their use of the sequence, for example, by advancing the sequence for each available subcarrier, such that the receiving device may view the payload as if it were sent by a single transmitter. Accordingly, these multiple transmissions may be descrambled using only one instance of a sequence generator.
