Title: Innovations of Wei Shi in Quantization Methods

Introduction

Wei Shi is an accomplished inventor based in Cambridge, GB. He has made significant contributions to the field of telecommunications, particularly in the area of quantization methods for Orthogonal Frequency Division Multiplexing (OFDM). His innovative approach has led to the development of a unique patent that addresses challenges in signal processing.

Latest Patents

Wei Shi holds a patent for a quantization method for OFDM. This method utilizes an objective function defined as a function of the quantization error of the OFDM signal in frequency, summed over data subcarriers. A search algorithm is employed to optimize the objective function, and the solution found is quantized by rounding. The quantized value of the solution can be fed back into the objective function to compute a new value. If this new value is less than the previous iteration's value, the method is repeated using the quantized value as the new starting point. If not, the new solution is discarded, and the previous quantized value is output.
