    Sammanfattning : With the advancement of wireless communication systems, the demand for higher data rates is increasing exponentially. Non Orthogonal Multiple Access (NOMA) is expected to play an important role in 5G new radio networks. In contrast to conventional multiple access schemes, NOMA allows different users to efficiently share the same resources (i.e. LÄS MER

  7. 10. Waveform agility for robust radar detection and jamming mitigation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Karl-Johan Hällgren; [2021]
    Nyckelord :radar; electronic warfare; jamming; jamming resistance; waveforms; phase codes; MIMO; radar; telekrig; störning; störskydd; vågformer; faskoder; MIMO;

    Sammanfattning : In this report metrics for jamming resistance and radar performance of waveform sets are described and developed, and different sets of waveforms are optimized, evaluated and compared. It is shown that without additional processing or PRI jitter, waveform sets can reach jamming resistance a few dB worse than what is provided by PRI jitter alone, and together with PRI jitter a few dB better.
