  Abstract

Multicast transmission, a way to accommodate multiple users‘ requests in a single transmission, can be utilized as one effective way to solve wireless traffic problems. Index coding, as a new multicasting scheme, has been shown to be able to effectively reduce wireless data traffic and various studies on index coding have been conducted in this regard. In multi-transmitter environments, several studies have been carried out only on how index coding techniques are applied to wired channels with fixed link capacity. However, there has been few study extended to wireless channel environments. In this paper, we propose an adaptive index coding technique for channels in multi-transmitter environments where storage capacity and channels differs in each users. To this end, we figure out decodable index codes according to the cache memory of each users and base station, and propose a brute-force algorithm to find the optimal base station cooperation and the corresponding optimal index code.
