Free standing linear arrays (FSLA) are analyzed and optimized to increase MIMO capacity. A MIMO channel model based on electric fields is used. The effects of mutual interactions among the array elements are included into the channel matrix using Method of Moments (MoM) based full-wave solvers. A tool to design an antenna array of superior MIMO capacity for any specified volume is developed. Pa...

Sparse linear arrays, such as co-prime and nested arrays, can identify up to O(M) sources with only O(M) sensors by using co-array based MUSIC. We conduct analytical performance analysis of two coarray based MUSIC algorithms, namely the direct augmentation based MUSIC, and the spatial smoothing based MUSIC. In addition, we analyze the Cramér-Rao bound for sparse linear arrays, and show that for...

This paper introduces balanced switching schemes to compensate linear and quadratic gradient errors, in the unary current source array of a current-steering digital-to-analog converter (DAC). A novel algorithm is proposed to avoid the accumulation of gradient errors, yielding much less integral nonlinearities (INLs) than conventional switching schemes. Switching scheme examples with different n...

Minimum Redundancy Linear Arrays (MRLAs) and Uniform (ULAs) investigation conducted with the possibility of using them in future 5G smart devices. MRLAs are designed to minimize number sensor pairs same spatially correlated delay. It eliminates selected antennas from entire composite antenna array preserves all possible spacing. have attractive features for linear sparse arrays, even if built-i...
