Description: Single Carrier FDMA又称SC-FDMA或者DFT-Spread-OFDM是3GPP LTE最新提出的适用于上行传输的一种新方案。相对于OFDMA（主要用于下行），其最大的优势在于低峰值平均功率比（即PAPR）。本程序包括OFDMA，SC-FDE（单载波频域均衡）以及SC-FDMA程序，接收端采用经典的ZF和MMSE检测算法，程序短小精悍，相当经典，方便该领域的人学习与研究。

Description: 数，都需要通过导频序列来获取同步信息，而且为了达到更好的均衡效果，OFDM 系统也要进行简单的频域均衡。此外，OFDM与SC．FDE的帧格式也十分相似，都 需要添加CP(SC．FDE采用UW)来吸收前面帧的干扰并满足循环卷积特性。 由于OFDM在结构和原理上都与SC．FDE十分相近，可以设计一种双模式系统。 双模式系统仅仅改变IFFT模块在发送端和接收端的位置就可以同时支持两种系统传 输。两种系统都可以通过编码、自适应调制和空间分集提高性能。而且，

Description: The main code is called "comparison of equalization schemes".
It uses functions, defined seperately to compute the bit error rate for different typs of equalizers.
That means times domain equalizer (TDE) with minimum mean square (MMSE) and zero forcing (ZF) algorithm,time domain decision feedback equalizer (DF_TDE) and linear frequency domain equalizer (FDE) with MMSE and ZF algorithms are used.For all simulations QPSK symbols and a tapped delay line channel with white gaussian noise are used.
Allthough the codes should be regarded as one package every single function can be of good use for other simulations.
With best regards,
Andreas

Description: This paper considers frequency-domain receiver design for OQPSK type schemes. Since the IQ Interference can lead to significant performance degradation we propose an FDE Design where there is no i-q interference in the sampling instants for the predominant OQPSK constellation. we also propose iterative FEDs with I-q interference cancellation as well as the cancellation of unintended OQPSK components.

Description: This paper considers receiver designs for
SC-FDE schemes (Single-Carrier with Frequency-Domain
Equalization) employing M-ary OQAM signals (Offset
Quadrature Amplitude Modulation). It is shown that the
interference between the in-phase (I) and quadrature (Q)
components at the sampling points can lead to severe
performance degradation. Therefore, receivers without
residual I-Q interference (IQI), as well as receivers with
IQI cancellation were developed. Our performance results
show that the new receivers are suitable to M-ary OQAM
schemes.
