This paper bringforths the concept of space time block codes for Non-Orthogonal Multiple Access (NOMA). Wireless communication networks are rapidly driven to meet the requirements interms of spectral/power efficiency. NOMA serves as promising technology in meeting these requirements by means of breaking orthogonality and serving all the users in same time/frequency domain by only differing in their power levels. In this paper, NOMA is combained with MIMO signal processing technique is proposed to improve the quality of the received signal. This paper compares the Bit Error Performance (BER) of two user NOMA system in existence of STBC and in devoid of STBC over Rayleigh fading channel. The simulation results show that the proposed system could give improved BER performance for the data stream multiplexed along with the main stream data even with imperfect Channel State Information.
