2012年10月19日 · Assuming a modulation order of 16 as a test case, we have compared 4 + 12-APSK and 16-QAM, in terms of both average and instantaneous BER, in a number of different …

Finally, the proposed USTLD schemes show bit error rate (BER) improvement over the existing two transmit USTLD scheme with error performance gain of 1.2 dB and 2.8dB at a BER of 10^ …

In this letter, a new amplitude phase shift keying (APSK) based M-ary differential chaos shift keying (A-M-DCSK) system is proposed. The theoretical symbol error rate (SER) and bit error …

2018年6月16日 · This paper investigates the design of power and spectrally efficient coded modulations based on amplitude phase shift keying (APSK) modulation with application to …

PSK, APSK, and QAM modulation schemes are widely used in communication systems. It is thus essential to know how well these schemes can perform in different fading channels. This …

2016年12月31日 · Bit error rate (BER) performance studies of amplitude phase shift keying (APSK) have not looked at the unequal error protection (UEP) facility provided by such a …

In the case of a general passive load and high SNR, the capacity-achieving distribution over the concentric circles in Fig. 5 is naturally resembled by amplitude and phase-shift keying (APSK)....

We evaluate the performance of APSK modulation for wireless systems and compare it with the performance of more conventional QAM systems. In previous literature, the analysis of APSK …

2018年9月4日 · BER. Bit Error Rate(BER) is usually considered by many to be the best measurement to verify receiver performance but BER testing is not always possible in the …

In this paper, we mainly focus on the frequency selective fading caused by delay extension in multipath effects, as well as the ISI and constellation distortion which the frequency selective …
