1Reliability

If compression sensing-based algorithms (l1 norm, l2 norm minimization, greedy iterative algorithm, approximate message passing) are used to detect reference signals, then the receiving end can recover transmitted data in many-to-one data transmission scenarios, but the computational complexity is relatively high due to iterative operations including matrix multiplication and complex multiplication

Solution Approach 1:

The patent segments the detection process by introducing a second reference signal that is orthogonal to the first reference signal. This orthogonality allows the receiving end to separately detect and process different reference signals, avoiding the need for complex iterative algorithms while maintaining detection accuracy in many-to-one scenarios

Inventive Principle:

Solution Approach 2:

The second reference signal acts as an intermediary that facilitates simpler detection. By providing an orthogonal reference signal, the system enables the receiving end to perform detection through direct correlation methods rather than complex iterative optimization, thus reducing computational complexity while preserving reliability
