Channel overloading in Code Division Multiple Access (CDMA) paves the way to achieve more no of users (>N) in a space with dimension equal to the spreading factor (N). It puts its own priority over the conventional CDMA to provide broadband access in cellular wireless communication. A new overloading scheme for the uplink of cellular CDMA has been proposed in [7] using unequal chip delay spreading...
Channel overloading in Code Division Multiple Access (CDMA) facilitates to accommodate more number of users than the assigned spreading factor N. Our proposal for a synchronous CDMA technique for the uplink of a cellular system over additive white gaussian noise (AWGN) channel achieves oversaturation by using the same set of orthogonal Walsh Hadamard codes and a receiver with lower complexity. The...
