Description: — Performance comparison of multiuser OFDM-TDMA and
OFDMA systems by considering physical and link cross-layer behavior
is conducted in this work. We provide a new framework for performance
evaluation that centers on “ scheduling” with several different
subcarrier/bit allocation schemes. The performance metrics include: the
bit rate, the bit error rate (BER), packet throughput and delay. The
instantaneous channel conditions of users are assumed to be available
at the base station, which can be achieved by channel estimation at the
mobile terminal (MT), and then fed back to the base station through
a control channel. To perform the link layer comparison, we model the
Rayleigh fading channel with a nite-state Markov chain, and adopt the
M/G/1 queueing model as the analytical tool. Computer simulation is
performed to verify conducted analytical results-— Performance comparison of multiuser OFDM-TDMA and

Description: The overall objective for LTE is to provide an extremely high performance radio-access technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks. OFDM/OFDMA technology is introduced for the LTE downlink, supporting very high data rates of up to 300Mbps while Single-Carrier FDMA (SC-FDMA) is used in the uplink with data rates of 80Mbps possible. Additionally, LTE supports operation both in paired and unpaired spectrum (FDD and TDD) using channel bandwidths of approximately 1.4MHz up to 20MHz. The frequency domain scheduling can be done in OFDMA. One of the main challenges in OFDMA is the high peak-to-average radio of the transmitted signal, which requires linearity in the transmitter. The linear amplifiers have low efficiency therefore, OFDMA is not an optimized solution for a mobile uplink where the -The overall objective for LTE is to provide an extremely high performance radio-access technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks.

Description: 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 term channel prediction, in both time and frequency, scheduling among users and smart antennas combined with adaptive modulation and power control. Frequency band is 2-8 GHz. it gives the ability for world-wide roaming to access cell anywhere.

Description: Long-Term Evolution (LTE) is a new standard speci ed by 3GPP for fourth generation (4G)
wireless communications. LTE provides high spectral eciency, high peak data rates, short
round trip time, and frequency
exibility. It relies on the following technologies Orthog-
onal Frequency Division Multiplexing (OFDM) and Multiple-Input and Multiple- Output
(MIMO), robust channel coding, scheduling and link adaptation [1]. LTE is interoperable
with widely used technologies such as GPRS, WCDMA and HSPA, and this enables mobile
operators deploying LTE to provide a seamless service and multimode devices for customers.
Some companies have already launched commercial LTE networks, e.g., Verizon Wireless in
the United States and Vodafone in Europe.
Here,the throughput of LTE physical layer in downlink transmissions is carried out. The various steps like CRC,turbo coding, code block segmentation,scrambling, modulation and precoding are also carried out.-Long-Term Evolution (LTE) is a new standard speci ed by 3GPP for fourth generation (4G)
