1. 36. On Spectrally Efficient Continuous Phase Modulation

   Författare :Tommy Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adjacent channel interference; additive white Gaussian noise {AWGN} ; convolutional codes; minimum Euclidean distance; continuous phase modulation CPM ; bandwidth efficiency; co-channel interference; reduced complexity detectors; optimized phase pulses.;

   Sammanfattning : Spectrally efficient partial response continuous phase modulation (CPM)for wireless links is considered. Continuous phase modulation defines constantenvelope phase codes, which are advantageous when using non-linear amplifiers. LÄS MER
