This paper shows a new communication system oriented to the future mobile communications, using concepts of security, sphere packing and channel gain. This system accomplishes the compression using sphere packing with support of Cab curves. At the same time, providing security and encrypting the information. Also with the use of code algorithms a high consistency is achieved. Finally, the performance of the system is shown as a function of SER (Symbol Error Rate) and SNR (Signal Noise Rate). In the first results, sphere packing modulation obtains a gain of 3.5 dB's compared with QPSK modulation with a SER = 10-6.
