Description: In this paper, a novel demodulation structure in
high-frequency (HF) channel is introduced and studied.Frequency-offset estimation, ractionally spaced adaptive equalization and carrier recovery techniques are involved.Frequency-offset correction is carried out based on channel impulse response estimation. ractionally spaced adaptive equalization and carrier recovery are combined with nonlinear decision feedback loop structure and the initial value
of tap coefficients of equalization are obtained from the previous channel estimation. Simulation is conducted under channel parameters with respect to MIL-STD-188-110B using a Monte Carlo technique. The results show this novel demodulation structure is feasible and efficient in HF channel, the symbol error ratio can reach to 10− 3 in 12dB SNR.-In this paper, a novel demodulation structure in

Description: 使用下面的参数设计信道均衡器，其中使用两个独立的随机数发生器，一个用x(n)来表示，用来测试信道；另一个用v(n)来表示，用来模拟接收器中的加性白噪声的影响。序列x(n)是x(n)=±1的伯努利序列，随机变量x(n)具有零均值和单位方差。第二个序列v(n)具有零均值，其方差由信噪比决定。均衡器有11个抽头。-Use the following parameter design of channel equalizer, which uses two separate random number generator, one with x (n) to indicate, to test the channel the other with v (n) to indicate to simulate the receiver in The additive white noise. Sequence x (n) is x (n) = ± 1 of the Bernoulli sequence of random variable x (n) with zero mean and unit variance. The second sequence v (n) has zero mean, its variance decision by the signal to noise ratio. There are 11-tap equalizer.

Description: The problem of channel equalization via channel
identification (CEQCID) that has previously been considered by a
handful of researchers is explored further. An efficient algorithm
for mapping the channel parameters to the equalizers coeficients
is proposed. The proposed scheme is compared with a lattice
least squares (LS) based receivers. For the particular application
of the high frequency (HF) radio channels, we find that the
CEQCID has lower computational complexity. In terms of the
tracking performance, also, the CEQCID has been found to be
superior to the LS based receivers [4]. We emphasize on the
implementation of a fractionally tap-spaced decision feedback
equalizer (DFE) and compare that with the T-spaced DFE of
[4]. We show that the former is a better choice for the multipath
HF channel-The problem of channel equalization via channel
