- OFDMA orthogonal frequency division multiple access SC-FDMA Uplink
Base station and the base station clock is not aligned when the interference is great
truncated bits, constellation mapping, inverse Fourier transform transmit signals (frequency domain to time domain), is superimposed on a plurality of time domain signals (uplink crest factor, burn base station device), uplink timing do Fourier transform (time domain to the frequency domain), the Capitol, inverse transform, superposition of a plurality of sub-carriers, PAPR is not so large.
- Multi-antenna capacity, mulching; interference coordination impact on network capacity and
multi-antenna is the MIMO, multiple-input multiple.
