MSK Modulation for Physical-Layer Network Coding Systems
Nan Sha, Yuanyuan Gao, Xiaoxin Yi, Wei Jian, Weiwei Yang · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2014
In this letter, we combine minimum-shift keying (MSK) with physical-layer network coding (PNC) to form a new scheme, i.e., MSK-PNC, for two-way relay channels (TWRCs). The signal detection of the MSK-PNC scheme is investigated, and two detection methods are proposed. The first one is orthogonal demodulation and mapping (ODM), and the second one is two-state differential detection (TSDD). The error performance of the proposed MSK-PNC scheme is evaluated through simulations.
