A RAKE Receiver With ICI/ISI Equalizer for CCK Wireless LAN Modem

Tags:
local area networks (lan)

Overview This paper proposes a new type of RAKE receiver for complementary code keying (CCK) codes, which is suitable for the multipath environment with large delay spread. As the delay spread is larger, Inter-Symbol Interference (ISI) and Inter-Chip Interference (ICI) generated due to multipath environments are increased. To handle the increasing ISI and ICI, CCK wireless LAN modem needs ISI and ICI cancellation technique, together with RAKE processing. So the proposed system is based on Channel Matched Filter (CMF) with Decision Feedback Equalizer (DFE) and includes codeword DFE structure. In the system, ICI and ISI are calculated by using detected CCK codeword. Also the proposed receiver uses the error correcting capability of CCK codes, and it can remove ISI and ICI at the same time.

The biggest VoIP security threats - and how to stop them

Ovum analyst Graham Titterington says: "A normal content filter won't work, although some pin their hopes on speech recognition. Certainly spammers wield enough power and would be enthusiastic adopters of a new voice channel to spread their message.

Trojan targets companies' top brass

The C-level nature of the targets clearly indicates that the attackers are after information, said the spokesman, but the greater concern is the social engineering technique used to spread the Trojan-harbouring email.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
