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.
Claims19
A method for communicating in one or more links of a communication network, the method comprising:
- transmitting a communication frame comprising a sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols, the sequence of N symbols encoding information in accordance with signal-to-noise ratio (SNR) associated with the communication frame, wherein the sequence of N symbols is selected from a set of four possible sequences of length N, and wherein the symbols for each of the four sequences are selected from a binary symbol alphabet consisting of a first symbol value and a second symbol value, and wherein a first sequence of the four possible sequences consists of N symbols of the first symbol value, and wherein a second sequence of the four possible sequences consists of N/3 symbols of the first symbol value followed by 2N/3 symbols of the second symbol value, and wherein a third sequence of the four possible sequences consists of 2N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value, and wherein a fourth sequence of the four possible sequences consists of N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value followed by N/3 symbols of the second symbol value.
A communication system comprising:
- a transceiver configured to transmit a communication frame comprising a sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols, the sequence of N symbols encoding information in accordance with signal-to-noise ratio (SNR) associated with the communication frame, wherein the sequence of N symbols is selected from a set of four possible sequences of length N, and wherein the symbols for each of the four sequences are selected from a binary symbol alphabet consisting of a first symbol value and a second symbol value, and wherein a first sequence of the four possible sequences consists of N symbols of the first symbol value, and wherein a second sequence of the four possible sequences consists of N/3 symbols of the first symbol value followed by 2N/3 symbols of the second symbol value, and wherein a third sequence of the four possible sequences consists of 2N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value, and wherein a fourth sequence of the four possible sequences consists of N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value followed by N/3 symbols of the second symbol value.
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 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, the sequence of N symbols encoding information in accordance with signal-to-noise ratio (SNR) associated with the communication frame and 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, wherein the sequence of N symbols is selected from a set of four possible sequences of length N, and wherein the symbols for each of the four sequences are selected from a binary symbol alphabet consisting of a first symbol value and a second symbol value, and wherein a first sequence of the four possible sequences consists of N symbols of the first symbol value, and wherein a second sequence of the four possible sequences consists of N/3 symbols of the first symbol value followed by 2N/3 symbols of the second symbol value, and wherein a third sequence of the four possible sequences consists of 2N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value, and wherein a fourth sequence of the four possible sequences consists of N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value followed by N/3 symbols of the second symbol value.
A method for communicating in one or more links of a communication network, the method comprising:
- receiving a communication frame comprising a sequence of N symbols, ensuing payload header symbols, and ensuing payload message symbols, the sequence of N symbols encoding information in accordance with signal-to-noise ratio (SNR) associated with the communication frame, wherein the sequence of N symbols is selected from a set of four possible sequences of length N, and wherein the symbols for each of the four sequences are selected from a binary symbol alphabet consisting of a first symbol value and a second symbol value, and wherein a first sequence of the four possible sequences consists of N symbols of the first symbol value, and wherein a second sequence of the four possible sequences consists of N/3 symbols of the first symbol value followed by 2N/3 symbols of the second symbol value, and wherein a third sequence of the four possible sequences consists of 2N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value, and wherein a fourth sequence of the four possible sequences consists of N/3 symbols of the second symbol value followed by N/3 symbols of the first symbol value followed by N/3 symbols of the second symbol value.
