... illustrations of the performance of the proposed algorithm. We assume all of the signals are equipower and have the same frequency. The numbers of the array elements in x-direction, y-direction, and z-direction ... algorithm for 2D DOA estimation only used the phase information of the signal. It can be inferred that the angular spread can be got from th...

... between K, N, and the SNR in terms of the CRB. In reality, the er- ror in the estimation is a combination of both model- and noise-induced errors. Let us therefore study the overall per- formance of our ... region K>3. Because of the insufficient parametrization of E, the RMS is higher for smaller values of K than the true K. The RMS decreases toward th...

... NT s is the duration of the useful part of the MC- CDMA block and G(i n ) is the frequency response of g(t)at the i n th subcarrier. In the sequel, we assume that the N u mod- ulated subcarriers ... sym- bols. The N u modulated subcarriers are located in the middle of the signal bandwidth and are divided into smaller groups of Q elements [17]. The remaini...
