Title: Olof E Grimlund: Innovator in CDMA Communications

Introduction

Olof E Grimlund is a notable inventor based in Bromma, Sweden. He has made significant contributions to the field of CDMA communications, holding a total of 3 patents. His work focuses on enhancing communication techniques through innovative methods.

Latest Patents

Grimlund's latest patents include "Multi-code compressed mode DS-CDMA systems and methods." This invention introduces discontinuous transmission in CDMA communications by selectively using additional spreading codes for data transmission. By dividing a frame into multiple portions and applying different spreading codes, the system allows for compressed mode transmission, optimizing the use of frame periods for other functions, such as frequency evaluation for handover.

Another significant patent is "Code-rate increased compressed mode DS-CDMA systems and methods." This invention also addresses discontinuous transmission by puncturing the coded output of a convolutional encoder. By temporarily increasing the coding rate, information fills only a part of the frame, leaving idle time for additional functions, such as frequency evaluation.
