Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal processing systems for DVB-T2 and FEF signals have redundant processing arrangements, leading to increased circuitry and power dissipation due to the need for separate detection and demodulation of T2 frames and FEF parts.
Innovation Solution
A signal processing apparatus with first and second detection means to identify and demodulate T2 and FEF signals based on preamble signals, reducing redundancy by sharing detection and demodulation information between signal processing blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate detection and demodulation arrangements are used for T2 frames and FEF parts, then each signal type can be processed independently, but the scale of circuitry increases and power dissipation increases
Solution Approach 1:
The patent merges the detection and demodulation arrangements into a shared configuration where a single detection unit detects preamble signals for both T2 frames and FEF parts, and a single demodulation unit processes both signal types. This consolidation eliminates redundant circuitry while maintaining the ability to independently process different signal types, thereby reducing overall circuit complexity and power consumption.
Solution Approach 2:
The detection unit is designed with universal functionality to detect preamble signals for multiple signal types (T2 frames and FEF parts) using the same hardware resources. The demodulation unit similarly performs multi-functionality by handling both T2 and FEF signal demodulation. This universal design allows one set of circuitry to serve multiple purposes, reducing the need for separate dedicated circuits for each signal type.
2Reliability
If separate detection and demodulation arrangements are used for T2 frames and FEF parts, then each signal type can be processed independently, but power dissipation increases
Solution Approach 1:
By merging the detection and demodulation functions into shared circuitry, the patent reduces the total number of active components that consume power. The shared detection unit and demodulation unit are activated only when needed for specific signal types, rather than maintaining separate always-on circuits for T2 and FEF processing, thereby reducing overall power dissipation.
Solution Approach 2:
The universal detection and demodulation units can dynamically adapt to process different signal types, eliminating the need for multiple dedicated power-consuming circuits. This multi-functional approach ensures that power is consumed only by the active processing unit rather than by multiple parallel circuits operating simultaneously.
3Reliability
If redundant processing arrangements are used for T2 and FEF signals, then independent signal processing is ensured, but processing efficiency decreases
Solution Approach 1:
The patent implements dynamic signal processing where the shared detection and demodulation units can dynamically switch between processing T2 frames and FEF parts based on the detected signal type. This dynamic adaptation allows the system to process signals efficiently without the overhead of maintaining static, dedicated processing paths for each signal type, thereby improving overall processing efficiency while maintaining independence.
