AI Technical Summary

Technical Problem

The increasing scarcity of spectrum resources and the increasingly stringent power consumption restrictions on uplink devices have led to insufficient communication reliability in mobile scenarios, necessitating the ability to withstand time-varying channel interference without increasing signal bandwidth and transmission power.

Method used

The SIMO-OTFS system using TCM coding combines a TCM modulator, a SIMO-OTFS modulator, a cyclic prefix addition module, and a transmitter. Through the design of TCM coded words and the OTFS modulation method, channel coding gain and time, frequency, and spatial diversity gain are achieved without increasing bandwidth and power.

Benefits of technology

Without increasing signal bandwidth and transmission power, it improves communication reliability, enhances anti-interference capability against time-varying channels, and improves frame error rate performance, making it suitable for high-speed mobile devices with limited power and bandwidth.
