OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

Spread spectrum modulation has been the basis for many proprietary and IEEE 802.11-based wireless LANs (WLANs). Through the use of frequency hopping and direct sequence, these WLANs provide data rates ...

In order to meet the ever increasing demand for larger transmission bandwidth, wireless network based on radio-over-fiber technologies is a very beneficial solution. The IEEE 802.11a standards using ...

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

German engineering and manufacturing giant Siemens AG is adding another broadband technology to its growing portfolio of new high-speed wireless systems slated for delivery early next year. Under an ...
