This project presents a complete end-to-end implementation of Quadrature Phase Shift Keying (QPSK) — a digital modulation technique used in real-world communication systems such as satellite, Wi-Fi, ...

Abstract: The transmission of amplitude phase shift keying (APSK) symbols through the spatial modulation (SM) scheme, i.e., the APSK-SM system, possesses the features of both the APSK and SM schemes.

len1 = floor(log2(factorial(Nt))); % Number of bits for the spatial (D) part len2 = Nt * b; % Number of bits for the PSK part len = len1 + len2; % Total number of bits transmitted per block blocks_per ...

Abstract: This paper investigates Binary-Phase Shift Keying (BPSK) based Time-Domain Single Carrier Index Modulation (TDSC-IM) optical signaling for next generation very high speed Passive Optical ...
