Implementation of a Wireless Multi-Carrier Acoustic Modem using Error Control Coding

چکیده
In Digital Communication Systems, especially high-speed modems, it is desirable to increase the bit rate while maintaining the same bandwidth without seriously impairing transmission quality. Single-Carrier systems provide a decent bit rate, but Multi-Carrier systems give bit rates that are several orders higher. Asymmetric Digital Subscriber Line (ADSL) services and Orthogonal Frequency Division Multiplexing (OFDM) are multi-carrier methods that are suited for this type of application. ADSL is used in two-wire line telephone services and OFDM is used in Wireless applications. Work done in a modem application that employs OFDM concepts and Reed-Muller Error Correcting codes is presented in this paper. The modem was implemented using the MATLAB numerical computation software package.

|We introduce a CDMA system based onmulticarrier spread spectrum (MC-SS) with one identical code for all users. In general, the employment of a multi-carrier transmission technique would increase the dynamic range of the correspondent lowpass time signal, and therefore would require a highly linear power ampli er. By carefully designing the code of a MC-SS signal a signi cant decrease of severa...
