Design a Trellis-Based Receiver to Combat CCI in EDGE Network

Abstract:

Like in GSM network the co-channel interference (CCI) is popular in EDGE network due to the problem of reusing frequency in distant cells. Although the distance between cells using the same frequencies is quite far but CCI still causes significant effect to the channel capacity rather than noise. In fact, many solutions were introduced to reduce the CCI accompanied with improving network capacity such as using MIMO scheme or SAIC scheme. The paper describes a novel receiver model which provides better performance than that of a SAIC system as well as smaller size and cost than a MIMO system. This proposed receiver uses two co-located antennas with difference polarizations to improve the total performance of the system. In addition, this receiver can be applied effectively in high-modulation scheme, for instant, 8-PSK modulation format in an EDGE network and /or in presence of more than one dominant interference.
