This paper presents the impact that gain, offset and timing mismatch in time-interleaved analog-to-digital converter (TIADC) have on digital receiver systems. An analysis of the mismatch errors shows the dependency of the different errors from the spectrum of the input signal. A discrete-time TIADC model is derived allowing to simulate the mismatch effects of the individual ADCs. Finally, simul...

This paper presents a cyclic prefixed conjugate transmission technique with adaptive receiver to cancel out the ICI in OFDM systems using MMSE equalizer. The receiver design is based on the phase rotated conjugate cancellation (PRCC) concept , where two individual phase rotations are employed on the two receive paths, rather than only one phase rotation is adopted for the two transmit paths in ...

This article focuses on the method of adjusting position unmanned aerial vehicles using bearings-only passive positioning. Based plane geometric relationship, a vehicle positioning model, circular queue adjustment scheme, and conical scheme are established, MATLAB is used to solve known data.Firstly, line connecting FY00 FY01 as polar axis coordinate system, sine theorem in triangle obtain func...

This paper presents the alignment of offset targets for five Taiwanese long tones, HH, LH, HL, ML, and MM, in different contexts. The location and value of offset target, in terms of f0 turning point, peak and valley, relative to the tonebearing syllable was studied. Corpus was sentences with five syllables. Tonal values of the second, third, and fourth syllables in these sentences were varied,...

This paper presents the first real-time experimental demonstration of a hybrid OFDM DFMA PON. The presented PON is validated for two channels (I or Q) occupying subwavelength bands. eliminates need dedicated matching filter at receiver each individual channel, by employing single FFT operation to recover all channels, thereby achieving lower computational complexity. used in conjunction with jo...
