OFDM modulator, OFDM demodulator, method of operating OFDM modulator, and method of operating OFDM demodulator

摘要

An OFDM modulator (1000) for operating in a wireless device (BS; UE) of a cellular radio communication network (RCN), comprising: a first and a second egress sample stream (e0, ..., eB-1, f0, ..., fB-1), the combined sample streams (g0, ..., gB-1) are determined and the combined sample streams (g0, ..., gB-1) are determined. ) Is proposed to up-convert the OFDM modulator to a carrier frequency higher than the respective sub-carrier frequency.
