Investigating the performance of an OFDM-based communication system with QPSK and QAM modulation and effects of AWGN and multi-path channels.

Here, the authors are proposing the FPGA based QPSK modulator with analog ... They have designed the system using VHDL codes in Xilinx & analog filter simulation in Matlab. Catch up on the latest ...

ABSTRACT: The manuscript developed an optimal frequency band transmission system structure of QPSK ... on Matlab. The experimental parameters used in the design are consistent with the requirements of ...

These codes are dasiabalancedpsila because they use the points of the constellation with the same probability. In this correspondence, we propose a new and simpler method than existing method to ...

Abstract: Achieving ultra reliable and low latency communication with short length information blocks has been an open research problem in the recent years. The bit ...
