Title: Sim Hak Keong: Innovator in VDSL Technology

Introduction

Sim Hak Keong is a notable inventor based in Singapore, known for his contributions to data transmission technologies. He holds 3 patents that focus on improving the efficiency of communication systems, particularly in the context of VDSL (Very-high-bit-rate Digital Subscriber Line) technology.

Latest Patents

One of his latest patents is centered around Trellis modulation protocols for a VDSL system. This innovative protocol proposes a method for transmitting data through lines such as telephone lines. The tones of a signal are grouped, and Trellis encoding is performed only on the members of a group. This approach significantly reduces the computational cost of coding and decoding data compared to treating all tones of a given direction equivalently. The invention also minimizes the computational and memory requirements of the encoder and decoder. Additionally, it ensures that Trellis decoding errors are not propagated between the groups, enhancing the reliability of data transmission.
