ifdma_tfrank
The Interleaved Frequency Division Multiple Ac-
cess (IFDMA) scheme is based on compression, repetition and
subsequent user dependent frequency shift of a modulated signal.
Multiple access is enabled by the assignment of overlapping but
mutually orthogonal subcarriers to each user. In this paper it
is shown that IFDMA can be regarded as unitary precoded
OFDMA with interleaved subcarriers. On the other hand,
IFDMA is shown to be a CDMA variant with frequency domain
orthogonal signature sequences and chip interleaving. Thus, it
combines the advantages of single and multi carrier transmission
such as low peak to average power ratio, orthogonality of the
signals of different users even for transmission over a time
dispersive channel and low complexity. Simulation results show
the good performance of coded IFDMA transmission over a
mobile radio channel for different data rates.

arconf
For an AR(p) model that has been fitted with ARFIT, [Aerr,werr]=ARCONF(A,C,w,th) computes the margins of error Aerr and werr such that (A +/- Aerr) and (w +/- werr) are approximate 95 confidence intervals for the elements of the coefficient matrix A and for the components of the intercept vector w. The input arguments of ARCONF are output of AR.

MSE
说明: 分析了相位噪声对正交频分复用(OFDM)系统的影响,发现相位噪声不仅产生 通用相角错误(CPE),而且还会产生载波间干扰(ICI),这都使OFDM系统的性能急剧恶 化,因此必须对CPE和ICI进行校正.文中给出了基于MSE准则的CPE校正方法,考虑到 ICI干扰主要来源于相邻信道,进而提出了基于LMS法则的自适应相邻信道干扰消除方 法.整个算法简单高效.仿真结果表明,所提出的算法大大改善了OFDM系统的性能(Phase noise is analyzed for orthogonal frequency division multiplexing (OFDM) systems, the influence of found that phase noise is not only a common phase error (CPE), but also produces the intercarrier interference (ICI), which makes the performance of OFDM system has evil, so must to CPE and ICI. CPE correction method based on MSE criterion are also given in this paper, considering the ICI interference is mainly from the adjacent channel, then was proposed based on the laws of LMS adaptive adjacent channel interference elimination The simulation results show that the proposed algorithm greatly improves the performance of OFDM system)
