  1. Performance analysis of two-way MAC layer network coding under finite relay buffer and non-negligible signalling overhead

    The paper analyzes practical two-way exclusive OR relaying systems, where finite relay buffer, non-negligible signaling overhead, and lossy wireless channels are considered. A two-layer Markov model is developed to characterize the practical two-way relaying systems, which is then reformulated into a two-dimensional Markov process after the projection and combination for the inter-layer state transitions of the two-layer model. The key performance parameters, such as throughput, queuing delay, and packet loss probability, are then derived.

    We study the performance of the fast frequency hopping/orthogonal frequency division multiplexing (FFH/OFDM) signal over frequency selective Rayleigh fading channel. We derive the decision variables and the signal-to-interference noise ratios (SINR) at the output of minimum mean square error (MMSE) and zero forcing (ZF) receivers. The results show that FFH/OFDM does not provide any diversity gain in case of ZF equalization. However, it brings significant diversity gain with the rise of number of sub-carriers (N) for MMSE equalization.

  3. A novel constellation amplitude modification method for PAPR reduction in OFDM systems

    Chunxing Ni, Yahui Ma and Tao Jiang

    Version of Record online: 17 NOV 2016 | DOI: 10.1002/wcm.2760

    In this paper, we propose a constellation amplitude modification (CAM) method to reduce the peak–to–average power ratio (PAPR) in orthogonal frequency division multiplexing systems. The key idea of the proposed CAM method is to modify the original constellation amplitude and choose the constellation points with the minimum PAPR as the transmitted constellation points. The CAM method formulates the PAPR reduction as a convex optimization problem, and then, it applies the customized interior–point method to solve the optimization problem.

  4. Adaptive joint precoding and pre-equalization with reduced complexity in massive MIMO systems

    Du Xiong, Wei Peng, Da Chen and Tao Jiang

    A joint precoding and pre-equalization with reduced complexity are proposed. The precoding process is adaptively switched on/off so that multiple users can be accommodated with the least cost of the computational complexity. About 90% of the computational complexity could be saved compared with the traditional scheme.

  5. Implementation and analysis of spectral subtraction in deterministic wide-band anti-jamming scenarios

    Travis Collins, Christopher Anderson and Alexander Wyglinski

    Version of Record online: 7 NOV 2016 | DOI: 10.1002/wcm.2751

    A new friendly jammer platform targeted against IED communications is proposed. This system provides in-band jamming of adversarial signals, while still maintaining friendly communication links. A feasibility study with software-defined radios demonstrates the proposed friendly jammer filtering technique over the air.
