Multicarrier modulation with OFDM for 4G networks
نویسنده
چکیده
This paper presents a new approach based on multicarrier modulation (MCM) with OFDM, to accomplish the goals of 4G. MCM [1] is a form of multicarrier system and a derivative of frequency-division multiplexing. MCM is a baseband process that uses parallel equal bandwidth sub channels to transmit information. Normally implemented with Fast Fourier transform (FFT) techniques, MCM's advantages include better performance in the inter symbol interference (ISI) environment, and avoidance of single-frequency interferers.

PAPR reduction of Coded OFDM signal using Selective Mapping Technique
Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation (MCM) technique which seems to be an attractive candidate for fourth generation (4G) wireless communication systems. Peak-to-average Power ratio(PAPR) problem is the major drawback of multicarrier transmission system which leads to power inefficiency.There are various techniques which can be used to reduce PAPR.In th...

The wireless medium has limited bandwidth, higher packet error rate, and higher packet overheads that altogether limit the capacity of the network to offer guaranteed QoS. OFDM systems, also referred as Multicarrier Systems, are known to be the basis of 3G and 4G technology, for example in LTE (Long Term Evolution) 4G cellular standards, WiMAX Standards, IEEE 802.11 a/g/n Microwave standards, e...
متن کاملUsing WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
