Binary CPMs With Improved Spectral Efficiency [PDF]
IEEE Communications Letters, 2016 We design new continuous phase modulation (CPM) formats which are based on the combination of a proper precoder with binary input and a ternary CPM. The proposed precoder constrains the signal phase evolution in order to increase the minimum Euclidean distance, and to limit the bandwidth expansion due to the use of a ternary CPM.

Spectral efficiency of spectrum-pooling systems [PDF]
IET Communications, 2008 In this contribution, we investigate the idea of using cognitive radio to reuse locally unused spectrum to increase the total system capacity. We consider a multiband/wideband system in which the primary and cognitive users wish to communicate to different receivers, subject to mutual interference and assume that each user knows only his channel and ...

A Comprehensive Performance Evaluation of Universal Filtered Multi-Carrier Technique
IEEE Access, 2019 The Internet of Things (IoT) and machine-to-machine (M2M) communication will play an important role in future communications, but there is currently no ultra-reliable low-latency wireless communication theory that guides its design.

Spectral efficiency of energy efficient multicarrier systems [PDF]
ACM SIGMETRICS Performance Evaluation Review, 2014 We investigate the achievable performances of multi-carrier energy efficient power control game. Both the simultaneous-move and the hierarchical games are addressed. For the first time, we derive analytical closed-form expressions of the spectrum coordination and the spectral efficiency of such models.

Integrated Framework to Study Efficient Spectral Estimation Techniques for Assessing Spectral Efficiency Analysis [PDF]
International Journal of Advanced Computer Science and Applications, 2017 The advanced network applications enable software driven spectral analysis of non-stationary signal or processes which precisely involves domain analysis with the purpose of decomposing a complex signal coefficients into simpler forms. However, the proper estimation of power coefficients over frequency components of a random signal leads to provide ...

IEEE Access, 2020 This paper analyzes the performance of the full-duplex (FD) multiple-input-multiple-output (MIMO) decode-and-forward (DF) relay system in the presence of self-energy recycling (S-ER). Specifically, this work proposes an antenna allocation scheme for S-ER

ACM Transactions on Graphics, 2019 We present a simple and efficient method for refining maps or correspondences by iterative upsampling in the spectral domain that can be implemented in a few lines of code. Our main observation is that high quality maps can be obtained even if the input correspondences are noisy or are encoded by a small number of coefficients in a spectral basis.
