Cocktail BPSK: Cross Power Utilization for High Data Rates. (arXiv:1809.10839v1 [cs.IT])
来源于:arXiv
This paper proposes a novel transmission strategy, referred to as cocktail
BPSK, where two independent BPSK symbols are layered with various weights to be
transmitted and, capitalizing on the cross power utilization, will be
demodulated at the receiver without interference from each other. To evaluate
the performance of the proposed scheme, its achievable data rate is formulated
over additive white Gaussian noise (AWGN) channels. Based on the theoretical
analysis, numerical results are provided for the performance comparisons
between the proposed scheme and conventional transmission schemes, which
substantiate the validity of the proposed scheme. Specifically, when the
signal-to-noise power ratio (SNR) is small, the achievable data rate of the
proposed scheme outperforms the channel capacity achieved by
Gaussian-distributed inputs. 查看全文>>
