Title: Arunhaba Ghosh: Innovator in Wireless Communication

Introduction

Arunhaba Ghosh is a notable inventor based in Austin, TX (US). He has made significant contributions to the field of wireless communication, particularly in the area of interference cancellation and receive diversity.

Latest Patents

Ghosh holds 2 patents, with his latest invention focusing on interference cancellation and receive diversity for single-valued modulation receivers. This innovative approach employs a combined SAIC receiver and a multiple-antenna, receive diversity receiver to effectively reduce interference in wireless systems. The method involves filtering the real and imaginary parts of the de-rotated signal for each receive path associated with an antenna. A combined output signal of all receive paths is generated, with weighting coefficients adjusted based on an error signal produced by comparing the combined output signal with a reference signal. The initial setting of these coefficients is based on an MMSE/LS type of signal processing criteria, where the reference signal is the Training Sequence Code (TSC). Subsequent adjustments can be made using known tracking algorithms, such as LMS or RLS, or by re-computing the coefficients using MMSE/LS processing.
