Channel Estimation TRIZ Cases
- Multi-Code-Set Channel Estimation for CDMA Interference Cancellation
Iterative multi-code-set channel estimation extracts maximum interference taps to cancel signals from neighboring cells.
- Dynamic Channel Assessment Mode for Unlicensed Band Access
A channel assessment mode activates aggressive transmission schemes based on detected interference triggers.
- CP Value Determination via Channel Estimation Feedback
Stations estimate physical channel conditions to determine required cyclic prefix values, allowing access points to select suitable parameters for each client.
- CM-Based Channel Status Information Enhancement
A base station reconstructs channel status information using a canonical model with selected kernels and basis sets.
- Preamble Sequence Prefix Suffix Multipath Interference Cancellation
Transmit end adds prefix and suffix to frequency offset estimation sequence for improved anti-multipath interference performance.
- Layered Detection for QAM-FBMC Frequency Equalization
A layered detection method segments QAM-FBMC equalization into one-tap recovery and interference cancellation layers to maintain symbol-level structure.
- FBMC Preamble Reference Signal Design for Channel Estimation
A preamble-based reference signal design leverages intrinsic interference in FBMC modulation to enable efficient channel estimation.
- Neural Network Channel Estimation Using Pre-Trained OSCC Parameters
Pre-trained neural network parameters classified by onsite channel characteristics reduce computational complexity and training effort for massive MIMO systems.
- MUI Cancellation via Phase Matrix in Wireless Systems
A base station accumulates channel values across tones to create a phase change matrix for multi-user interference cancellation.
