Engineering Contradiction Analysis
1Area of stationary object
If the distance between transmitter and receiver is increased, then the coverage area is expanded, but the reception performance of the signal decreases
Solution Approach 1:
The patent applies preliminary action by pre-generating multiple candidate convolution patterns and storing them in a buffer before they are needed for signal processing. This allows the system to quickly select and apply appropriate patterns when processing received signals at various distances, maintaining reception performance across extended coverage areas without requiring real-time pattern generation.
2Reliability
If signal processing complexity is increased to improve reception performance, then the reception performance increases, but the device complexity increases
Solution Approach 1:
The patent merges the functions of pattern generation, pattern storage, and pattern selection into an integrated convolutional encoder system. By combining these functions and pre-generating patterns, the system achieves improved reception performance through complex signal processing while avoiding the proportional increase in device complexity that would result from implementing these functions separately in real-time.
