WebAug 14, 2013 · Furthermore, we introduce the concept of outage in OFDM radar networks, which will become the basis of further analyses. When designing an OFDM radar network, we must make sure to satisfy the assumption that all interference can be modeled as AWGN (this becomes relevant for the derivations in Section 4). 3.1 Time-slotted multi-user access WebAn OFDM modulator converts a high-rate serial stream of symbols into many parallel low-rate streams. Each orthogonal low-rate stream encounters a relatively flat channel with minimal ISI, and can be easily equalized. To demonstrate, consider a pulse of duration T sym = 0. 25 sec, a symbol data rate R sym = 1 / T sym = 8 Hz, and additional ...
