Abstract
Methods and transceivers transmit communication frames that comprise a sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols. The sequence of N symbols encodes information according to signal-to-noise ratio associated with the communication frame.
Claims17
A method for communicating in one or more links of a communication network, the method comprising:
- transmitting a communication frame comprising a binary sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols, the binary sequence of N symbols encoding information in accordance with signal-to-noise ratio (SNR) associated with the communication frame, and wherein the binary sequence of N symbols is selected from a set of four binary sequences of length N, and wherein the set of four-binary sequences of length N is chosen from all possible sets of four binary sequences of length N such that the minimum Hamming distance of the set of four binary sequences of length N is maximized, wherein the communication frame includes a superframe header consisting of L symbols that consists of a first segment of L-N symbols and a second segment that consists of the binary sequence of N symbols, and wherein the encoded information is included in the second segment of symbols, and wherein L is 720 and N is 216.
A communication system comprising:
- a transceiver configured to transmit a communication frame comprising a binary sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols, wherein the binary sequence of N symbols encodes information in accordance with signal-to-noise ratio (SNR) associated with the communication frame, and wherein the binary sequence of N symbols is selected from a set of four binary sequences of length N, and wherein the set of four binary sequences of length N is chosen from all possible sets of four binary sequences of length N such that the minimum Hamming distance of the set of four binary sequences of length N is maximized, wherein the communication frame includes a superframe header consisting of L symbols that consists of a first segment of L-N symbols and a second segment that consists of the binary sequence of N symbols, and where in the encoded information is included in the second segment of symbols, and wherein L is 720 and N is 216.
A method for communicating in one or more links of a communication network, the method comprising:
- transmitting a communication frame that comprises a header including a binary sequence of N symbols, and one or more ensuing communication sub-frames, each communication sub-frame including a plurality of repeated blocks of payload header symbols followed by blocks of payload message symbols, wherein the binary sequence of N symbols encodes information in accordance with signal-to-noise ratio (SNR) associated with the communication frame and is indicative of a repetition factor to be applied to the blocks of payload header symbols, in each communication sub-frame, necessary to decode a corresponding number of the blocks of the payload message symbols, and wherein the binary sequence of N symbols is selected from a set of four binary sequences of length N, and wherein the set of four binary sequences of length N is chosen from all possible sets of four binary sequences of length N such that the minimum Hamming distance of the set of four binary sequences of length N is maximized, wherein the communication frame includes a superframe header consisting of L symbols that consists of a first segment of L-N symbols and a second segment that consists of the binary sequence of N symbols, and wherein the encoded information is included in the second segment of symbols, and wherein L is 720 and N is 216.
A method for communicating in one or more links of a communication network, the method comprising:
- receiving a communication frame comprising a binary sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols, wherein the binary sequence of N symbols encodes information in accordance with signal-to-noise ratio (SNR) associated with the communication frame, and wherein the binary sequence of N symbols is selected from a set of four binary sequences of length N, and wherein the set of four binary sequences of length N is chosen from all possible sets of four binary sequences of length N such that the minimum Hamming distance of the set of four binary sequences of length N is maximized, wherein the communication frame includes a superframe header consisting of L symbols that consists of a first segment of L-N symbols and a second segment that consists of the binary sequence of N symbols, and wherein the encoded information is included in the second segment of symbols, and wherein L is 720 and N is 216.
