GSM network is seeing its greatest expansion because of the growing demand for mobile voice services inemerging markets recently while maintaining backward compatibility with the legacy system A newly proposedtechnology , Voice services over Adaptive Multiuser channels on One Slot (VAMOS) feature has the potential to doublevoice capacity of the existing GSM mobile communication system while maintaining backward compatibility with thelegacy system would help operators in densely populated cities to alleviate the strain on their networks concept ofMUROS is based on multiplexing two or more users onto one time slot without degrading the speech quality is based onOrthogonal Sub-Channel (OSC) approach. Lot of research work is dedicated to signal generation and especially to newreceiver concepts as well as power control in order to implement VAMOS transmissions. The aim of our work is toimplement a model system able to evaluate performance parameters related to downlink transmission in VAMOS.The model implements generation of the VAMOS modulated signal with power control and receiving solutions based ona modified MLSD (Maximum Likelihood sequence Detector) structure that allows comparison of performances inVAMOS downlink transmission.
