Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external wiring and switching matrices are used for routing channel signals, then signal routing between antenna signals and radio channel units is achieved, but the structure becomes complex and reliability decreases
Solution Approach 1:
The patent merges the routing function and signal processing function into a single integrated radio channel unit. Each radio channel unit directly receives antenna signals and performs both routing and channel simulation, eliminating the need for separate external wiring and switching matrices. This integration reduces structural complexity while improving reliability by removing numerous external connection points that are prone to failure.
Solution Approach 2:
The radio channel unit is designed as a multi-functional module that simultaneously performs signal routing, channel simulation, and signal processing. This universal design allows a single component to fulfill multiple roles that previously required separate dedicated components, thereby simplifying the overall system architecture and reducing the number of external connections required.
2Reliability
If external wiring is used for routing channel signals, then signal transmission between components is achieved, but the system becomes prone to failure
Solution Approach 1:
By combining the routing and processing functions within the radio channel unit, the patent eliminates numerous external wiring connections. The signals are routed and processed internally within the integrated module, significantly reducing the number of external connection points that are susceptible to failure from loose connections, interference, or physical damage.
3Ease of operation
If complex switching matrices and adders are used for routing and combining signals, then signal routing and combination is achieved, but the structure becomes complex
Solution Approach 1:
The patent merges the switching matrix and adder functions directly into the radio channel unit's internal architecture. This integration allows signal routing and combination to be performed within the processing module itself, eliminating the need for separate external switching matrices and adders, thereby simplifying the overall system structure while maintaining full functionality.

AI summary
The invention provides a device for simulating a multi-antenna radio channel, a module and a method. The device comprises channel modules for incorporating propagation effects into channel signals which represent radio signals propagating along propagation paths, which channel modules are electrically connected to neighbour channel modules for forming an (m,n) array configuration. The (m,n)th channel module is configured to receive a first (m,n−1)th channel signal and a second (m−1,n)th channel signal and comprises: a processing resource for processing the first (m,n−1)th channel signal according to a channel model, thus generating a processed (m,n)th channel signal, and a combiner for combining the processed (m,n)th signal and the second (m−1,n)th channel signal, thus generating a second (m,n)th channel signal. The (m,n)th channel module is further configured to output the second (m,n)th channel signal.
