The paper presents a new wireless communication system using Chirp Spread Spectrum (CSS) transmission. The applied modulation scheme is extended with Pulse Position Modulation (PPM) to transmit data for multiple mobile terminals simultaneously. The proposed system is a Low-Power Wide-Area Network (LPWAN) providing very reliable and robust transmission, especially for terminals moving with high speeds...
The application of network coding in wireless environment provides a new horizon for throughput enhancement. By means of network coding the throughput of a network can be increased very efficiency. In this paper we use a family of constant dimension subspace codes called lifted rank-metric coding (LRMC) and investigate its performance in a general wireless environment. LRMC process reduces the number...
