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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encoding and modulation systems and methods for ultra low signal to noise ratio wideband radio frequency communication","description":"Systems and methods for the secure transmission of data and algorithms are disclosed.
