This paper proposes an interference alignment scheme, called linear interference alignment, for the fully connected $K$ user interference channel, where the delays from the interference user are assumed to be arbitrary discrete value. To increase the probability of the successful interference alignment, for a given delay profile, the parameters {\it pseudo random seed} and {\it offset vector } are introduced in LIA with these searching algorithms. Geometrical representation of LIA is also given for evaluating its performance and, the analysis results shown that LIA can achieve asymptotically $1/2$ degree of freedom for each user for arbitrary but fixed discrete delay. |
