Simple Space-Time Block Code Encoding

This is a straightforward implementation of Space-Time Block Code (STBC) encoding, featuring the fundamental orthogonal Alamouti encoding technique. The Alamouti scheme utilizes spatial diversity through multiple antennas combined with coding principles to enhance reliability and performance in wireless communication systems. In this encoding program, the implementation typically involves organizing two consecutive symbols (s1, s2) into a 2×2 transmission matrix: [s1, -s2*; s2, s1*], where * denotes complex conjugation. This structure enables transmission over two time slots using two antennas without requiring channel state information at the transmitter. The code implementation would include functions for symbol pairing, complex conjugation operations, and matrix formation to achieve improved signal quality and interference resistance without increasing system complexity. Thus, orthogonal Alamouti encoding remains a widely adopted and extensively researched critical technology in wireless communications, particularly valued for its full-rate transmission and simple decoding requirements.
