....bit channels. It is possible to measure the relative delays by transmitting the same sequence of bits over all the bit channels simultaneously and then comparing the sequences received on individual bit channels. A pseudo white noise binary sequence 2 has good properties for word synchronization [17], and binary circular correlation is adequate for comparison of the received sequence, since circular correlation is performed by simple Exclusive NOR logic and accumulation. One can train the compensator by sending a training frame that contains R bit pseudo random sequences. This training method ....

....issues and their related technology will be discussed in Section 3. 2. 1 Digital Wireless Communication System Regardless of the particular application and configuration, all information transmission systems invariably involve three major subsystems a transmitter, the channel, and a receiver[10]. To transmit digital information from a transmitter to a receiver, four steps are usually concerned in such a system: Coding, Ciphering, Multiplexing, and Modulation. Coding is used for two purposes: representing the data more efficiently and or generating codes that are more resistant to noise. ....
