TDD Technology Flexible in spectrum: Requires unpaired frequency bands only • It is difficult to find paired frequency bands under 2 GHz Same frequency for uplink and downlink: Smart antenna can be used Support asymmetric service Low cost for Node B • Lower power PA with smart antenna High spectrum efficiency leveraged by Smart Antenna, JD and TDD Page 10
Orthogonal Frequency Division Multiplexing 25. 892 Figure 1: Frequency-Time Representation of an OFDM Signal OFDM is a digital multi-carrier modulation scheme, which uses a large number of closely-spaced orthogonal sub-carriers. Each sub-carrier is modulated with a conventional modulation scheme (such as QPSK, 16 QAM, 64 QAM) at a low symbol rate similar to conventional single-carrier modulation schemes in the same bandwidth.
