MIMO - OFDM – Multi input and multi output orthogonal Frequency Division Multiplexing, AWGN – Adaptive White Gaussian Noise, CP – Cyclic prefixing, Channel Estimation, DWT- Discrete Wavelet Transform, BER – Bit Error Rate

In OFDM multiple carriers’ square measure used and it provides higher level of spectral potency as compared to Frequency Division Multiplexing (FDM). In OFDM as a result of loss of orthogonality between the subcarriers there's repose carriers put downference: Inter carrier Interference (ICI) and inter symbol interference (ISI) and to beat this downside use of cyclic prefixing (CP) is needed, that uses two hundredth of obtainable information measure. Comparison between typical and traditional standard} FFT/DCT based mostly} OFDM systems with DWT based OFDM system are created in line with some conventional and non-conventional modulation ways over AWGN. The ripple families are used and compared with FFT/DCT {mostly based or based mostly primarily based mostly} OFDM system and located that DWT based OFDM system is best than FFT/DCT based OFDM system with regards to the bit error rate (BER) performance.
