VLSI Implementation of OFDM Modem
White Paper This results in the optimal usage of bandwidth. OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. A set of orthogonal sub-carriers together forms an OFDM symbol. [25 Jun 2007]
Concatenated Codes Design for OFDM Based Wireless Local Area Networks
White Paper The advantages of OFDM systems are high spectrum efficiency, longer symbol duration against Inter-Symbols Interference (ISI) effect in multi-path environments, and narrow transmission band of each sub-carrier within coherence bandwidth such that... [11 Apr 2007]
Throughput and Coverage of WLANs Employing STBC Under Different Channel Conditions
White Paper HIPERLAN/2 and 802.11a/g WLANs employ Coded Orthogonal Frequency Division Multiplexing (COFDM) to provide data rates of up to 54 Mbps in a 20MHz bandwidth. In this paper, Space-Time Block Coding (STBC) techniques are considered as a means of... [09 Feb 2006]
Integrated Performance Analysis of PCF and DCF Schemes Over IEEE 802.11a Physical Layer
White Paper Even though the channel bandwidth has significantly increased with this standard, the mechanism used to govern media access is still based on the IEEE 802.11 MAC protocol. IEEE 802.11a is one of the latest Physical layer (PHY) standards to be... [17 Jan 2006]
Architecture and Scheduling Algorithm for a Multi-Channel Wireless Infrastructure Network With Diversity Management Layer
White Paper This paper proposes a "super" Wi-Fi network architecture, which uses the multiple non-overlapping channels simultaneously to improve the total network bandwidth with minimum changes to the existing devices. [10 Jan 2006]
CSR goes for Wi-Fi with chip launch
News The requirement for bandwidth is going up and the number of applications that want to use bandwidth is going up," said James Collier, CSR's technical director. Cambridge Silicon Radio (CSR) has launched a range of chips that support the three most... [09 Nov 2004]
