In this paper, we present two microwave devices at 1 GHz for next-generation wireless communication systems. The first device is a magnet-less circulator that consists of three resonant branches connected in a delta topology and spatio-temporally modulated with 120 deg phase difference between each other. The proposed circulator is fully compatible with standard CMOS technologies and holds the promise...
The current use of algebraic space-time block codes (STBC) such as Golden Codes and Integer Codes (ICs) in multiple-input multiple-output (MIMO) wireless communication systems is limited by the decoders' lack of ability to produce log-likelihood ratios (LLRs) for compatibility with the state-of-art soft-input forward error correction codes (FEC). In this paper, we show that ICs can be described as...
