Method for using Concatenated Convolutional Turbo Codes in IEEE 802.16a

Tags:
802.11

Overview Turbo codes present a new and very powerful error control technique, which allows communication very close to the channel capacity. Since its discovery in 1993, a lot of research has been done in the application of turbo codes in deep space communications, mobile satellite/cellular communications, microwave links, paging, in OFDM and CDMA architectures. This paper proposes a method for using concatenated convolutional Turbo codes for 802.16a. These concatenated convolutional turbo codes are optimized for each constellation size.

Femtocells to speed arrival of next-gen mobile networks?

Saunders added: "It isn't a technology that we think is specific to just one of the flavours of mobile air interface - UMTS or GSM or CDMA or WiMax, for that matter - we actually think femotcells bring things to all those technologies.

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?
