    Abstract: Embodiments of the present disclosure relate to system and method for generating a waveform in a communication network is disclosed. The method comprises determining precoder information using one of an indication from a base station and predetermined parameters corresponding to precoding. The predetermined parameters are one of coefficients of the precoding filter, and flatness requirement of the precoding filter. Also, the method comprises generating a sequence of output modulation symbols, wherein each output modulation symbol is obtained using a block of input data symbols and a lookup table. The lookup table is a function of the precoder information and pre-determined modulation information. Next, the sequence of output modulation symbols is transformed using Discrete Fourier Transform to generate transformed output modulation symbols. Thereafter, mapping the transformed output modulation symbols using a plurality of subcarriers to generate a sub-carrier mapped symbols and processing the sub-carrier mapped symbols to generate a waveform.

    Abstract: Embodiments of the present disclosure relate to a method and system to selecting a waveform in a communication network. The method comprises selecting at least one sequence from a plurality of sequences for transmitting, said plurality of sequences comprises a plurality of sub-set of sequences such that a sequence in a sub-set of sequences is a cyclic shifted version another sequence in said sub-set of sequences. Also, the method comprises rotating at least one sequence from a plurality of sequences by 90 degrees to produce at least one rotated sequence. Further, the method comprises transforming the at least one rotated sequence into frequency domain using a Discrete Fourier Transform (DFT) to generate a transformed sequence and mapping the transformed sequence using a plurality of subcarriers to generate a mapped sequence. Thereafter, the method comprises processing the mapped sequence to generate a waveform having an optimized PAPR, optimized auto and cross-correlation.

    Abstract: Embodiments of the present disclosure are related to a receiver and a method for receiving signal. The method comprises estimating, by a receiver, channel for each of a plurality of antennas using the received signal stream, to produce a plurality of estimated channels. Also, method comprises grouping a predetermined number of received signals from the received signal stream and estimated channels associated with the received signals to obtain a plurality of groups. Further, a group specific filtering is performed on the received signals and corresponding estimated channels of each of the plurality of groups to obtain filtered received signals and a plurality of filtered estimated channels. Thereafter, the method comprises performing second filtering on all the filtered received signals to produce second filtered signals, which are processed to produce an output.

    Abstract: Embodiments of the present disclosure relates to a method and system to schedule a pool of resources to a plurality of user equipment's (UEs). The method comprises grouping the UEs using inputs from UEs, to obtain a plurality of groups. Also, method comprises determining a pivot UE from the UEs using a first metric associated with each of the UEs, associated with a selected group from the plurality of groups. Further, the method comprises pairing the pivot UE with at least one UE using a second metric, wherein the at least one UE is associated with the selected group. Next, precoding weights are determined for each of the plurality of UE's associated with the selected group. Thereafter, transmitting data and reference signals associated with each UE associated with the selected group, using the corresponding precoding weights on a sub-set of pool of resources.
