WiMAXin-ofdm
- Reaching Higher data rate and spectral efficiency are among the challenges expected for 4G wireless systems. Combining OFDM modulation and multiple-input multipleoutput (MIMO) help for that. In this paper, performances of a WiMAX MISO-OFDM based syst
OFDM-Report
- Modern wireless communication systems are expected to support high data rate, allowing users to access high quality multimedia content, anytime-anywhere. To support high data rate, wideband frequency channels are required. However, frequency selectiv

- As a multicarrier transmission system Orthogonal frequency division multiplexing (OFDM) has been widely applied in wireless communication systems due to its numerous advantages like robustness against multipath fading and delay, high data rate tr
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
BER-ANALYSIS-IN-OFDM
- Multi-Carrier Modulation is a technique for data-transmission where a high-bit rate data stream is divided into several parallel low bit-rate data streams and using these low bit-rate data streams to modulate several carriers. Multi-Carrier Transmiss

- Simulation and performance analysis of OFDM with different modulation techniques A special case of multicarrier transmission is Orthogonal Frequency Division Multiplexing (OFDM).In which single data stream is transmitted over a number of lower rate
Frequency-Hopped-Multiple-Access-Communications-W
- A noncoherent, bandwidth-efficient modulation scheme is proposed for frequency-hopping multiple-access (FH-MA) networks. The proposed scheme is a combination of noncoherent -ary amplitude-shift keying (NMASK) and orthogonal frequency-division
3-ici-diminution
- In a rapidly fading environment in high data rate wireless communication systems the orthogonality of OFDM sub carrier signals destroyed and this phenomenon potentially results in Inter carrier interference (ICI).The novel contribution of the paper i
Optimum_OFDM_Receiver_1
- basic concept of OFDM is quite simple [4]–[7]. Data is transmitted in parallel on a number of different frequencies, and as a result the symbol period is much longer than for a serial system with the same total data rate. Because the symbol perio
introduction-to-OFDM-1
- Orthogonal Frequency Division Multiplexing (OFDM) is one of the latest modulation techniques used in order to combat the frequency-selectivity of the transmission channels, achieving high data rate without inter–symbol interference. The basic pri
