Abstract: Wireless media, which is commonly used for advertising purposes, should be constructed in a manner which reduces the required access time and the cost for the receiver. In this paper, two families of orthogonal codes are presented as means to deliver information based on CDMA technology. The data stream that contains pages and links is coded with a unique set of Walsh-Hadamard (WH)functions, while the whole data stream of a particular base station is coded using Bent sequence, another lass of binary coding sequence, called Bent sequence. Numerical results are presented and show that a system using Bent coding exhibits significant improvement in performance in terms of bit error rate and potential number of simultaneous users in comparison with other sequences.
