In fourth-generation (4G) wireless communication and its famous long-term evolution (LTE) technology, multiple input, multiple output (MIMO) plays a great role. It offers a profound impact on affording high data rate communication as the most salient aspect of 4G, solely or in the carrier aggregation style. Proceeding with massive MIMO techniques would definitely be a valuable source of achievements for 5G as well.

Plenty of methods have been proposed to utilize the spatial diversity of the aforementioned technology in a more effective manner. These ideas have mostly concentrated on modulation and coding techniques to mitigate the destructive effects of inter-channel interference. With this aim, the paper proposes an idea not only to suppress the co-channel interference but surmount a famous limitation of MIMO, that is, the maximum number of transmitting streams is equal to the minimum number of antennas at the transmitter or receiver.

A preprocessing routine is proposed to eliminate co-channel interference. Two important points are noticeable: 1) the complexity of the proposed system increases rapidly as the number of transmitting antenna enhances, and 2) the reasoning concern with interference cancellation is somehow vague; many processing components are mentioned without their functional description.

While a well-structured paper, the presentation of the core is not mature, concrete, or robust enough. Furthermore, there is no optimistic view in its implementation as an applicable technique.
