Viterbi Decoding Strategies for 5 GHz Wireless LAN Systems

Tags:
local area networks (lan)

Overview Standards for the operation of Wireless Local Area Network (WLAN) technology in the 5 GHz band have been developed in Europe, North America and Japan. These systems employ Orthogonal Frequency Division Multiplexing (OFDM) technology, and utilize Forward Error Correction (FEC) coding, based on a 1/2-rate convolutional encoder, to combat frequency selective fading caused by multipath channels. This paper examines methods, based on the popular Viterbi algorithm, for Maximum-Likelihood (ML) decoding of this convolutional code within the WLAN baseband receiver. Although the paper focuses on the European HIPERLAN/2 standard, because of international Physical (PHY) layer harmonization, the work is equally applicable to the North American and Japanese WLAN systems.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
