Description: 该模型实现了一个通用的OFDM TX和RX，这是不依赖于任何特定的行业标准。该模型的目标是开发和研究不断（不是“突发”）载波同步和定时跟踪方案。该技术纳入然后可以扩展和修改，以标准的具体通讯套件。该模型采用了“收购”技术，它利用了循环前缀相关属性，以赶在试图完成罚款跟踪算法一帧的边界粗略的估计。该模型实现了一个16点64循环前缀的OFDM载波波形。在OFDM符号有16个飞行员，3后卫音（0，带边幅），并使用45 QAM的剩余数据流4。
这包括最新型的衰落信道，误码率计算，并改善控制回路动态。-This model implements a generic OFDM TX and RX, which is not tied to any particular industry standard. The objective of this model is to develop and explore a continuous (not “bursty”) carrier and timing tracking synchronization scheme. The techniques incorporated can then be extended and modified to suite specific communications standards. The model uses an “acquisition” technique that exploits the correlation properties of the cyclic prefix to get a rough estimate of the frame boundary before attempting to accomplish the fine tracking algorithms. The model implements a 64 carrier OFDM waveform with a 16 point cyclic prefix. The OFDM symbol has 16 pilots, 3 guard tones (0 amplitude at band edge) and uses 4 QAM for the 45 remaining data streams.
This latest model includes a fading channel, BER computation, and improved control loop dynamics.

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: With the increasing demand of higher data rate for telecommunication, the IEEE802.11n standard was constituted in 2009. The most important character of the standard is MIMO-OFDM, which not only improves the throughput but also the spectrum efficiency and channel capacity. And in wireless communication, the role of MIMO detectors plays an important part to remove inter-symbol interference (ISI) caused by multipath fading channel. In this paper the BER performance of IEEE 802.11n for 3x2, 4x2 and 4x3 antennas are compared using MMSE and ZF detectors in Matlab Simulink.
