Mixed-Mode MIMO Detector Sub-Channel Allocation

The patent applies local quality by differentiating detection approaches across different sub-channels based on their specific channel conditions. Linear detectors are assigned to sub-channels with low correlation where they provide sufficient performance with lower complexity, while non-linear detectors are assigned to sub-channels with high correlation where their superior signal resolution capability is needed. This localized adaptation resolves the contradiction by optimizing the match between detector capability and channel requirements.

The patent changes the parameter of detector type selection based on channel correlation characteristics. By evaluating channel conditions and dynamically assigning appropriate detector types (linear vs. non-linear) to different sub-channels, the system adapts its processing complexity to match the actual signal conditions, thereby achieving good signal resolution only where necessary while reducing overall processing burden.

The patent implements local quality by applying different detection strategies to different sub-channels based on their correlation properties. Sub-channels with low correlation use computationally efficient linear detectors that process quickly, while sub-channels with high correlation use more accurate but computationally intensive non-linear detectors. This resolves the time-accuracy contradiction by ensuring high accuracy is achieved only where channel conditions warrant it.

The patent applies partial action by using non-linear detectors only for the portion of sub-channels that require their enhanced capability (those with high correlation), rather than applying them universally. This selective application reduces overall processing time while maintaining detection accuracy where it matters most, avoiding the excessive processing time that would result from universal non-linear detector deployment.

The patent resolves this contradiction by making detector selection local to each sub-channel's characteristics. Linear detectors are deployed on sub-channels with low correlation where they provide adequate performance with minimal complexity, while non-linear detectors are deployed on sub-channels with high correlation where signal resolution capability is compromised by using linear detectors alone. This localized differentiation ensures neither complexity nor resolution capability is suboptimal.

The patent changes the detector type parameter based on channel correlation measurements. By evaluating the correlation parameter of each sub-channel and selecting the appropriate detector type accordingly, the system ensures that signal resolution capability is maintained in high-correlation channels while keeping processing complexity low in low-correlation channels, thus resolving the contradiction between these two parameters.

The patent applies local quality by allocating detectors based on local channel characteristics rather than using a uniform allocation strategy. Each sub-channel is evaluated for its correlation properties, and detector type is selected locally to match those conditions. This provides adaptability to varying channel conditions while maintaining relatively simple device complexity through automated selection logic, resolving the contradiction between uniformity and adaptability.

The patent introduces dynamics into the detector allocation process by making detector selection dependent on channel conditions rather than being static and uniform. The system dynamically evaluates channel correlation and adjusts detector allocation accordingly, enabling adaptability to varying channel conditions while keeping the overall device complexity manageable through systematic selection criteria.
