Abstract: Systems and methods for the secure transmission of data and algorithms are disclosed. The coding and modulation schemes meet the need of low signal-to-noise (SNR) ratio applications in areas of high interference. A radio transmitter is used to transmit data signals and a radio receiver is used to receive signals. The new coding algorithms and modulation for wideband communication at very low SNR domains. Systems use orthogonal frequency-division multiplexing modulation and a channel pilot algorithm for timing synchronization and frame alignment. Systems also use an orthogonal code, a super orthogonal convolutional code, and a block code to achieve channel capacity within 80% of the Shannon limit in the subzero decibel (dB) domain with reasonable decoding complexity. In an implementation example given, a 12.5 MHz band radio can transmit at a 108 kbps user data rate at ?20 dB SNR and escape adversity detection.
