1. A system (110) for facilitating improved sector throughput, said system comprising:
one or more processors operatively coupled to a plurality of user equipments (UE), said plurality of UEs further having a downlink communication channel with a multi-input multi output (MIMO) base-station,
wherein the one or more processors (202) that executes a set of executable instructions that are stored in a memory (204), upon execution of which, the processor (202) causes the system (110) to:
receive, a set of data packets from the plurality of UEs (104), said set of data packets pertaining to downlink (DL) feedback communication signals from each UE;
extract, a first set of attributes from the received set of data packets, the first set of attributes pertaining to a DL Block Error Rate (BLER) in each said UE;
determine, based on the extracted first set of attributes, an average BLER of each said UE;
compare the determined average BLER of each said UE with a predetermined target BLER;
determine if each said UE is allocated with a resource block (RB) containing a direct current (DC) subcarrier;
increase a DC subcarrier power level in the RB containing the DC-subcarrier up to a maximum pre-determined level if the determined average BLER is greater than the predetermined target BLER in a UE and the UE is allocated with the resource block (RB) containing the DC subcarrier module.
