Diversity Combining Terrestrial Receiver for Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for delivering non-satellite content (terrestrial content) to satellite customers are costly, cumbersome, power-hungry, expensive, inflexible, and inefficient.
Innovation Solution
A system and method for diversity combining using a terrestrial receiver with multiple antennas and full spectrum capture receivers, which diversity combines terrestrial television channels and remodulates them for efficient transmission to customer premises equipment, employing coarse FFT processing and channel or band stacking to generate maximum ratio combined co-phased signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing methods are used to deliver terrestrial content to satellite customers, then content delivery is achieved, but the system becomes costly, cumbersome, power-hungry, and inefficient
Solution Approach 1:
The patent replaces traditional terrestrial signal reception mechanisms with a satellite-based direct broadcast system. Instead of using ground-based infrastructure (mechanical/systemic approach), the invention utilizes satellite transmission to deliver content directly to customer premises, eliminating the need for complex terrestrial signal processing and multiple conversion stages, thereby reducing power consumption and improving efficiency
Solution Approach 2:
The invention extracts the content delivery function from the terrestrial infrastructure and relocates it to satellite-based transmission. By separating the content delivery path from traditional terrestrial systems, the patent eliminates cumbersome intermediate steps and reduces dependency on ground-based power-intensive equipment
2Productivity
If existing methods are used to deliver terrestrial content, then content delivery is achieved, but the system becomes costly and expensive
Solution Approach 1:
The patent creates a multi-functional satellite broadcast system that can deliver various types of content (terrestrial TV, data, etc.) through a single infrastructure. This universal approach eliminates the need for separate dedicated systems for different content types, reducing overall system cost and improving manufacturing efficiency
3Adaptability or versatility
If existing methods are used for content delivery, then delivery is achieved, but the system becomes inflexible
Solution Approach 1:
The patent implements a dynamic content delivery system where the satellite can transmit content that is selectively received and processed at customer premises. The system can adapt to different content types, transmission formats, and customer requirements without requiring complex reconfiguration of the entire delivery infrastructure, thereby improving flexibility while managing complexity

AI summary
A terrestrial receiver at a premises includes a plurality of antennas and a corresponding plurality of tuners. The terrestrial receiver receives terrestrial television signals via the plurality of antennas and the plurality of tuners and diversity combines a corresponding plurality of terrestrial television channels within the received terrestrial television signals, for example, based on control signals received from one or more customer premises equipment (CPE). The terrestrial receiver processes the diversity combined corresponding plurality of terrestrial television channels and communicates the processed and diversity combined corresponding plurality of terrestrial television channels to the one or more CPE. The diversity combined corresponding plurality of terrestrial television channels may be remodulated, and converted to corresponding analog signals prior to being communicated to the one or more CPE. The diversity combined corresponding plurality of terrestrial television channels may be demodulated and converted to intermediate frequency signals prior to being communicated to the one or more CPE.
