Distortion-free Golden Precoded Alamouti for MISO Systems
Although the discrete Fourier transform (DFT) precoded Alamouti (DPA) scheme with limited feedback offers numerous benefits in the Rayleigh fading channel, this scheme inherently generates geometric mean distortion due to the error exponential of the DFT precoding (DP). Consequently, the receiver suddenly losses the average received channel power. Instead of the conventional DPA scheme, we prop...
متن کاملComparison of BER for BPSK & QAM modulation with Alamouti STBC
On comparing the error performance of various space-time block codes(STBC) for the quasi-static Rayleigh fading channels and with different modulation techniques as BPSK,QAM, it is observed that the slope of BER is steepening as Eb/N0 is increased. It is also observed that a higherorder diversity is obtained with a larger number of transmit antennas, that is, steepening the slope of BER curves ...
متن کاملAlamouti-Based Space-Frequency Coding for OFDM
We investigate space-frequency block coding for OFDM systems with multiple transmit antennas, where coding is applied in the frequency domain (OFDM carriers) rather than in the time domain (OFDM symbols). In particular we consider Alamouti’s code, which was shown to be the optimum block code for two transmit antennas and time domain coding. We show that the standard decoding algorithm results i...
متن کاملGolden Angle Modulation: Approaching the AWGN Capacity
In this work, targeting, e.g., future generation cellular, microwave-links, or optical fiber systems, we propose a new geometric shaping design for golden angle modulation (GAM) based on a (double) truncated Gaussian input distribution. The design improves the mutual information (MI), and the peak-toaverage power ratio, over the full signal-to-noise ratio (SNR) range relative to two key GAM sch...
متن کاملGeneralized golden ratios of ternary alphabets
Expansions in noninteger bases often appear in number theory and probability theory, and they are closely connected to ergodic theory, measure theory and topology. For two-letter alphabets the golden ratio plays a special role: in smaller bases only trivial expansions are unique, whereas in greater bases there exist nontrivial unique expansions. In this paper we determine the corresponding crit...
