This paper investigates a Modified Uniform Triangular Array (MUTA) to support online space-time MIMO-CDMA location based services with full azimuthal coverage via JADE-MUSIC algorithm. A new Space-Time Lifting Preprocessing (STLP) scheme is introduced as a decorrelating process of coherent signals through the dense/NLOS multipath MIMO channel before applying the JADE-MUSIC estimator. Uniform-H-Array (UHA) and Uniform-X-Array (UXA) geometries are established for performance comparisons with the proposed MUTA. Computer simulations under environment Matlab are described to illustrate the performance of online joint angle/delay estimation with MUTA-MIMO base station applying JADE-MUSIC in conjunction with STLP scheme in 360? azimuth region.
