本文介绍了OFDM基本原理,并分析了多径信道下的OFDM信号,通过在发送端采用符号内2DPSK调制,在接收端相应地采用符号内2DPSK解调,可使接收数据的误码率降低。 关键词:OFDM多径信道2DPSK调制2DPSK解调 1引言 正交频分复用[1](Orthogonal Frequency Division Multiplexing,OFDM)是一种特殊的多载波调制技术,由于OFDM技术是...
In this, a new approach for data modulation DPSK-OFDM is introduced, and its performance is evaluated to compare with other standard methods of barcode modulation. OFDM uses orthogonal subcarrier and confine image blur & minimizes the Bit Error Rate. OFDM modulation is performed using DFT. 展开...

IFFT is replaced by Inverse Discrete Wavelet Transform (IDWT) and FFT is replaced by DWT (Discrete Wavelet Transform) in the conventional OFDM.DPSK modulation scheme is used in this work. In this paper both FFT OFDM and DWT OFDM are compared in the presence of Carrier Frequency Offset (CFO)...
A Doppler diversity receiver for OFDM is proposed by Kim B C[1], which requires channel estimation at the receiver, so its structure is complicated, what's more, the receiver needs a large amount of calculation. Different from it, we use the differential phase modulation technology in the ...
We propose the generation, detection, and label swapping methods for DPSK-labelled OFDM transmission. Without increasing the signal bandwidth, we show the attached label has almost no influence on the superior performance of OFDM payload.Wei-Ren Peng...
