Simulation Analysis of 4G/5G OFDM Systems by Optimal Wavelets with BPSK Modulator

LTE (Long-Term Evolution) is one of the appropriate technologies to sever requirement IoT (Internet Things) together with mobile UE (User Equipment), because priority services, high data rate, low latency, etc. has received OFDM for transmission it meets necessity LTE-like range flexibility and empowers cost gainful responses wide carriers. offers big-data values, allows spectrum reframing, reduces cost, We proposed a 4G/5G adopted based on multi-equalizer BPSK (Binary-Phase Shift Keying). The BER (Bit Error Rate) system reduced through optimal wavelet coefficient at transmitter side. This obtained by applying DWT (Discrete Wavelet Transform) input signal BFF (Binary Firefly) algorithm. serial parallel process carried out modulation. At last, like MMSE (Minimized Mean Square Error) MLE (Maximum Likelihood) applied model reduce BER. analyzed using parameter SER (Symbol Rate), spectral efficiency, MSE (Mean Error), methodology provides better outcome than other existing approaches.
