In this paper, multi-cell channel estimation algorithm based on successive interference cancellation (SIC).This channel algorithm is also used for Time Division Synchronization Code Division Multiple Access Systems (TD-SCDMA). TD-SCDMA is the country's standard of 3G mobile telecommunication. This reduces the number of users in each timeslot, which reduces the implementation complexity of multi...

ABSTRACT The paper presents design of a 2×2 multiple input multiple output (MIMO) LTE Downlink using OFDM with 16-QAM scheme, operated in a spatial Multiplexing (SM) mode. An urban Microcell Winner channel model is assumed to investigate the performance of the system. The focus of this paper is to understand the effect of antenna spacing of end transceivers on the performance of 2×2 MIMO LTE Do...

In this review paper, we analyze the performance of Channel estimation problem for TD-SCDMA System. The conventional channel estimation algorithm currently used in the TD-SCDMA system. Parallel interference cancellation (PIC) channel estimation algorithm by simultaneously eliminating the interference of adjacent cells and improve the accuracy of channel estimation. Accurate information of chann...

We propose Joint Spatial Division and Multiplexing (JSDM), an approach to multiuser MIMO downlink that exploits the structure of the correlation of the channel vectors in order to allow for a large number of antennas at the base station while requiring reduced-dimensional Channel State Information at the Transmitter (CSIT). This allows for significant savings both in the downlink training and i...

Turbulence in natural environments affects the reliability of communication. In this paper, we propose a symmetric matrix-assisted multiple-input multiple-output (MIMO) maritime visible light communication (VLC) system to confront turbulence and improve reliability. our design, by exploiting repeatability elements matrix, matrix can expand Euclidean distance between signals effectively restrain...
