Multilevel Space-Time Codes on Hoyt Fading Channel
International Research Journal on Advanced Science Hub,
2020, Volume 2, Issue 6, Pages 75-78
AbstractMultilevel space-time trellis codes with multiple inputs and multiple outputs under the presence of the Hoyt fading in the communication channel are illustrated. The spectral efficiency shoots higher substantially if a code is spread out at more than one level, due to the fact that bandwidth used to transmit more symbols is same as that used to transmit less symbols in case of a single level system. Complexity of decoding a system with more than one level increases but using a multistage decoder it can be dealt with. The resultant system with multiple levels of coding and multiple stages of decoding maintains the balance between spectral efficiency and decoding complexity with desirable error performance.
