4GG
- The 4g wireless uses Orthogonal Frequency Division Multiplexing (OFDM), Ultra Wide Radio Band (UWB), and Millimeter wireless. Data rate of 20mbps is employed. Mobile speed will be up to 200km/hr. The high performance is achieved by the use of long te
Channel-Equalization-via-Channel-Identification-A
- The problem of channel equalization via channel identification (CEQCID) that has previously been considered by a handful of researchers is explored further. An efficient algorithm for mapping the channel parameters to the equalizers coeficie

- Vandermonde-subspace Frequency Division Multiplexing for Two-Tiered Cognitive Radio Networks
tcvr
- Personal Communications Services (PCS) require low-power radio technologies. One such transceiver architecture employing frequency-hopped spread spectrum techniques is described. Low power and robustness are two keys to a wireless personal comm
Channel_MIMO-OFDM_system
- CDMA (OFDM-CDMA), offers several key advantages such as immunity against narrowband interference and robustness in frequency-selective fading channels[2]. Such desirable properties make MC-CDMA an attractive choice for the present and future radio-co
[5]-Sensitive-White-Space-Detection-with-Spectral
- This paper proposes a novel, highly effective spectrum sensing algorithm for cognitive radio and white space applications. The proposed spectral covariance sensing (SCS) algorithm exploits the different statistical correlations of the received
InTech-Accelerating_radio_wave_propagation_algori
- Radio is the use of radio waves to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.[n 1] When radio wave
OFDM-1
- To fully exploit wireless radio resource and, thus, increase spectrum efficiency, cognitive radios shall sense wire- less environments and identify interference to allow opportunis- tic transmissions for secondary systems. Based on Chen et al.
