[File Format] DOA-Estimation DL : 0: 一篇非常实用的无线通信方向的文献，是关于cdma系统中doa估计的经典-The use of antenna arrays in wireless communications makes it possible to estimate the directions of arrival (DOAs) of impinging waveforms. The latter can be exploited to enhance channel estimation accuracy or as an input for advanced mobile positioning systems. In this paper, we consider the uplink of a multicarrier code-division multiple-access (MC-CDMA) network in which the base station is endowed with multiple receiving antennas arranged in a uniform linear array. Transmission takes place over a multipath channel, and the goal is the joint estimation of the channel responses and DOAs of the uplink signals. In doing so, we follow a maximum-likelihood (ML) approach and assume that users transmit orthogonal training sequences to facilitate the task of separating the signals. This way, all unknown parameters are estimated independently of each other with affordable complexity. Theoretical analysis and computer simulations are used to assess the performance of the propose

[File Format] A-Search-free-DOA-Estimation-Algorithm-for-Coprim DL : 0: In this paper, a fast search-free method for direction-of-arrival (DOA) estimation with coprime arrays was proposed. It is based on the use of methods that operate on the uniform linear subarrays of the coprime array and that enjoy many processing advantages. We rst estimate the DOAs for each uniform linear subarray separately and then combine the estimates the subarrays. For combining the estimates, we propose a method that projects the estimated point in the two-dimensional plane onto one-dimensional line segments that correspond to the entire angular domain. By doing so, we avoid the search step and consequently, we greatly reduce the computational complexity of the method. We demonstrate the performance of the method with computer simulations and compare it with that of the FD-root MUSIC method.- In this paper, a fast search-free method for direction-of-arrival (DOA) estimation with coprime arrays was proposed.
