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又称SC-fdma或者DFT-Spread-OFDM是3GPP LTE最新提出的适用于上行传输的一种新方案。相对于Ofdma(主要用于下行),其最大的优势在于低峰值平均功率比(即PAPR)。本程序包括Ofdma,SC-FDE(单载波频域均衡)以及SC-fdma程序,接收端采用经典的ZF和MMSE检测算法,程序短小精悍,相当经典,方便该领域的人学习与研究。
