[Communication-Mobile] MIMO-OFDM-Systems-Based-on-Preamble- DL : 0: MIMO􀀁 OFDM 技术将成为第4 代移动通信系统的关键技术, 因MIMO􀀁 OFDM 对时间和频率偏移非常敏感, 因此MIMO􀀁 OFDM 同步显得尤为重要。提出了一种新的MIMO􀀁 OFDM 定时同步和频偏同步技术。以GCL 序列为基础设计了一个新的符合MIMO􀀁 OFDM 同步技术的导频序列, 通过对该导频序列进行2 次相关得到频率估计, 并将所得频率运用到定时同步中, 得到更为准确的时间估计。仿真结果表明, 在相同的信噪比情况下, 该方法可以使得系统的误码率和帧传送误码率相对传统方法得到进一步减小。-MIMO􀀁 OFDM will become a key technology of the fourth generation mobile communications system. However, MIMO􀀁 OFDM is sensitive to the CFO and timing synchronization, so the MIMO􀀁 OFDM synchronization technology is very important. This paper proposes an accurate technique for timing and frequency synchronization of multiple􀀁 input multiple􀀁 output ( MIMO ) orthogonal frequency division multiplexing ( OFDM) systems. The technique derives a new preamble signal based on GCL sequences, according with the MIMJO􀀁 OFDM synchronization. The carrier frequency offset ( CFO) estimation is obtained through taking double correlation operations on the preamble signal, and used in the timing synchronization to gain accurate time estimation. The simulation results show that at the same SNR, the proposed method can reduce the BER and the frame transmission BER of the system compared to the conventional method.

[Other] Ber-Analysis-Of-Ieee80211n-Mimo-System-Using-Mmse DL : 0: 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.

The combination of multiple-input-multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) techniques have been adopted in recent wireless standards, such as 802.11x families, to provide higher data rate. Because MIMO uses antenna arrays, beamforming can be adopted to improve the received signal to noise ratio (SNR) which in turn reduces the bit error rate (BER).)
