In this paper we propose a Multiple-SIgnal-Classification (MUSIC) based algorithm for joint direction finding and delay estimation of the impinging rays in the presence of antenna mutual coupling. We show that with the addition of auxiliary sensors on both sides of the antenna array the algorithm developed earlier can be extended to this scenario. The new algorithm also consists of three stages of...
In this paper, we propose an efficient algorithm to jointly estimate the directions of arrival (DOAs) and carrier frequency offsets (CFOs) in interleaved orthogonal frequency division multiple access / space division multiple access (OFDMA/SDMA) uplink networks. The algorithm makes use of the signal structure by estimating the CFOs and DOAs in a hierarchical tree structure, in which two CFO estimations...
The high-density deployment of access points (APs) and their serious mutual interference have made both frequency acquisition and data detection even more difficult in wireless local area network (WLAN). In light of this, this paper presents an antenna-array-assisted algorithm to solve above problems in a multiuser multiple-input-multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM)...
