There are two crucial aspects those define fundamental restrictions in data transmission channels. One of them is the spectral bandwidth limitation and the other is robustness to noise at error free data transmission speeds. Pattern Based Communication System (PBCS) targets to handle these restrictions. It involves a new modulation and encoding technique that adaptively uses collection of weakly correlated signal pattern sets called glossaries. Each glossary in the glossary space is indexed regarding to classification of two components: the transmission capability under the specified noise suppression in terms of Signal to Noise Ratio (SNR) and Link Spectral Efficiency (LSE) (bps/Hz), which consists of the utilized spectral bandwidth (Hz) by the test signal pattern and its data bit rate (bps).
