In this paper, we propose header detection technique for massive internet of things (IoT) networks over Rayleigh fading channels. We consider coded random access (CRA) as a multiple access scheme for IoT to keep low computational complexity of detection, where header detection is of significant important. We perform header detection by computing cross correlation using Hadamard codes. Hadamard codes...
Phased Multiple-Input Multiple-Output (PMIMO) radar which uses overlapped noncoherent transmit subarrays and noncoherent receive arrays provide better performance in transmit-receive gain and SINR than Phased Array and MIMO radar. This paper shows PMIMO approach which uses a coherent receive array provides the same performance as other radars but is more efficient in its use of matched filters and...
In the uplink system, different carrier frequency offsets (CFO) of different users at the receiver resulting multiuser interference (MUI) and thus degrade the performance of Multicarrier Code Division Multiple Access (MC-CDMA) system. In the previous study, Modified Minimum Mean Square Error Frequency Domain Equalization (Modified MMSE-FDE) has been proposed by Agnihotri which results in a better...
