Abstract :
We address the problem of combining two potential capacity enhancing techniques in the future TDMA mobile systems: slow random frequency hopping between co-channel cells and interference cancellation of the dominant interferer by joint detection. The former technique is based on the averaging the interference between all users leading to the so-called interference diversity gain. The latter technique can enhance the receiver performance by performing joint demodulation for the desired and interfering signals. We study the combination of the two techniques by radio link and network simulations to quantify the total capacity gain
