BPSK OFDM Modulation Bit Error Rate Analysis in OFDM Systems
OFDM (Orthogonal Frequency Division Multiplexing) is a digital multi-carrier modulation scheme based on Frequency Division Multiplexing (FDM). It utilizes numerous closely-spaced orthogonal subcarrier signals to transmit data through multiple parallel data streams or channels. Each subcarrier employs conventional modulation schemes like Phase Shift Keying (PSK) or Quadrature Amplitude Modulation (QAM) at low symbol rates, while maintaining an overall data rate comparable to traditional single-carrier modulation schemes within the same bandwidth. This article provides MATLAB implementation examples for BER simulation using BPSK-OFDM modulation over AWGN and Rayleigh channels, including the relationship between Eb/No and Es/No ratios.
