Engineering Contradiction Analysis
1Reliability
If a plurality of hardware lines are used for signal transmission between high-frequency and intermediate-frequency integrated circuits, then signal transmission reliability is improved, but hardware cabling resources are excessively occupied
Solution Approach 1:
The patent combines multiple signal transmission functions into a single hardware line by using a diplexer. The diplexer allows communication signals and control signals to share the same physical transmission line, reducing the number of hardware lines needed while maintaining signal transmission reliability through frequency separation and filtering.
Solution Approach 2:
The diplexer enables a single hardware line to serve multiple functions: transmitting both communication signals (IF signals) and control signals (instruction data and echo clock) between the high-frequency and intermediate-frequency integrated circuits. This multi-functionality reduces hardware cabling requirements.
2Quantity of substance
If hardware lines are reduced between integrated circuits, then hardware cabling resources are saved, but design flexibility of flat cable and hardware connector is limited
Solution Approach 1:
The patent changes the frequency parameters of signals to enable multiplexing. By assigning different frequency ranges to communication signals and control signals, and using the diplexer to separate them, the system achieves both hardware line reduction and design flexibility. The frequency parameter differentiation allows the same physical line to carry multiple signal types.
3Object-affected harmful factors
If multiple signals are transmitted through separate hardware lines, then signal interference is minimized, but hardware complexity increases
Solution Approach 1:
The diplexer acts as an intermediary device between the high-frequency and intermediate-frequency integrated circuits. It mediates the transmission of multiple signals by separating them based on frequency, allowing communication signals and control signals to share a hardware line while minimizing interference through its filtering function.

AI summary
Embodiments of this application provide a wireless communication system and an electronic device, and relate to the field of wireless communication technologies, to resolve a problem that there are a large quantity of hardware lines for transmission between a high-frequency integrated circuit and an intermediate-frequency integrated circuit. A first high-frequency integrated circuit in the wireless communication system includes a high-frequency control unit, a first diplexer, and a second diplexer. An intermediate-frequency integrated circuit includes an intermediate-frequency control unit, a third diplexer, and a fourth diplexer. A control signal is transmitted between the high-frequency control unit and the intermediate-frequency control unit. The control signal includes an instruction data signal and an echo clock signal. A phase of the instruction data signal is synchronized with a phase of the echo clock signal, and a frequency of the instruction data signal and a frequency of the echo clock signal are in a co-frequency relationship or a frequency multiplication relationship. The echo clock signal is transmitted between the high-frequency control unit and the intermediate-frequency control unit via the first diplexer and the third diplexer, and the instruction data signal is transmitted between the high-frequency control unit and the intermediate-frequency control unit via the second diplexer and the fourth diplexer.
