High bit rate and more security for physical layer are very important today therefore they grow and evolution because of the large size media and accuracy of the information transmitted now, But that cannot be changing generation systems every time, Therefore we need a programmable system and immediate change by re-change protocol or changes completely through programming devices to become much more affordable, customizable for costumer users and Consecration; Therefore we propose the physical layer system that can be programmable using the system that already work like LTE-OFDM, W-CDMA, CDMA2000 … etc. this system is using n-QAM and n-QPSK as base data instead off 1,0 binary system but transmitter by MC-CDMA or OFDM-CDMA (MC-DS-JCDMA) in both H-Polarity and V-Polarity waves with more security using JPN instead off PN. The results were without channel estimator or equalizer acceptable in 24dB with high bit rate and low bandwidth in both selective and flat fading channel added with AWGN and Doppler Effect.
