IngeniArs has developed a 4D-8PSK-TCM Transmitter IP core that combines 4-Dimensional modulation and 8-Phase Shift Keying with Trellis coding, providing significant benefits in terms of error correction and spectral efficiency. This technology is widely used in satellite communications for both broadcasting and data services. The integration of Trellis Coded Modulation (TCM) enhances error correction, minimizing the impact of noise and interference. The 4D-8PSK-TMC Encoder and Modulator IP core provides a complete and configurable solution for medium data-rate communications compliant with ECSS-E-ST-50-05C standard. The IP core is capable of producing 4 symbols in parallel.
