Abstract
This paper develops a new achievable region for the K-user symmetric interference channel using algebraic interference alignment. Our scheme uses lattice codebooks to transform the interference channel into an equivalent noiseless discrete-alphabet additive interference channel. Subsequently, algebraic alignment schemes are used to characterize the achievable rates for this channel.
