Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices are limited to operating in a single communication protocol mode, lacking flexibility to adapt to different communication protocols and operation modes, such as MP-HSDPA, Type3, Type3I, MIMO, and STTD, which restricts their compatibility and efficiency in diverse communication systems.
Innovation Solution
A unified, programmable receiver system that can operate in multiple modes by incorporating programmable modules for channel estimation, frequency offset compensation, and timing adjustment, allowing it to receive and process signals according to various protocols and modes, including MP-HSDPA, Type3I, MIMO, and STTD, through a combination of hardware and software configurations.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional communication devices are configured to operate in a single communication protocol mode, then the device structure is simple and easy to manufacture, but the adaptability to different communication protocols and operation modes is limited
Solution Approach 1:
The receiver is designed with programmable modules that can be configured to operate in multiple communication protocols and operation modes (MP-HSDPA, Type3, Type3I, MIMO, STTD) through software configuration rather than requiring separate hardware for each mode. The receiver includes programmable channel estimation modules, frequency offset compensation modules, and timing adjustment modules that can be selectively activated based on the desired operation mode.
Solution Approach 2:
The receiver employs dynamically reconfigurable modules that can change their operational characteristics based on the selected communication mode. The channel estimation module can switch between different estimation algorithms, the frequency offset compensation can adjust its parameters, and the timing adjustment module can modify its synchronization approach depending on whether the receiver is operating in Type3, Type3I, MIMO, or STTD mode.
2Adaptability or versatility
If a unified programmable receiver with multiple modes is implemented, then the adaptability to different communication protocols is improved, but the device complexity increases
Solution Approach 1:
The receiver is divided into distinct functional modules: channel estimation module, frequency offset compensation module, timing adjustment module, and signal processing module. Each module is independently programmable and can be selectively activated or deactivated based on the operation mode, allowing complex functionality to be achieved through modular composition rather than monolithic design.
Solution Approach 2:
The receiver manages complexity by changing operational parameters and configuration settings rather than requiring different hardware structures for each mode. The same physical receiver can be reconfigured for Type3, Type3I, MIMO, or STTD operation by adjusting parameters such as channel estimation algorithms, frequency offset compensation settings, and timing synchronization parameters.
3Productivity
If conventional receivers operate in a single mode, then the manufacturing cost is lower, but the productivity and efficiency in diverse communication systems are reduced
Solution Approach 1:
The receiver is designed as a universal platform that can operate in MP-HSDPA, Type3, Type3I, MIMO, and STTD modes, enabling deployment in diverse communication systems and improving cell-edge throughput through optimized processing for each mode. The programmable architecture allows the same device to be manufactured and deployed across multiple network types without requiring separate hardware variants.

AI summary
Techniques are described herein that receive communications transmitted according to different operation modes at a multi-mode, programmable receiver system. The multi-mode, programmable receiver system may receive communication signals from transmit antennas in “cells” (e.g., base station transceivers and/or the like) according to one or more operation modes, using receive antennas. The received signals may be converted and processed by various modules of the multi-mode, programmable receiver system to produce an output signal. The multi-mode, programmable receiver system includes modules that are programmable to be selectively enabled or disabled according to an operation mode in accordance with which the multi-mode, programmable receiver system operates.
