This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University.
The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.
Single Carrier FDMA又稱SC-FDMA或者DFT-Spread-OFDM是3GPP LTE最新提出的適用于上行傳輸的一種新方案。相對于OFDMA（主要用于下行），其最大的優勢在于低峰值平均功率比（即PAPR）。本程序包括OFDMA，SC-FDE（單載波頻域均衡）以及SC-FDMA程序，接收端采用經典的ZF和MMSE檢測算法，程序短小精悍，相當經典，方便該領域的人學習與研究。
