                               ABSTRACT

In this talk, we present a capacity approximation within O(1) result
for a class of single input multiple output (SIMO) Gaussian interference
channels. Before presenting the result, we first introduce an idea of
successive approximations of capacity of interference networks that have
emerged throughout recent research on interference channel. Taking this
idea, we study the N+1 user, 1 x N SIMO Gaussian interference channel
where each transmitter has a single antenna and each receiver has N
antennas. The generalized degrees of freedom and capacity within O(1) are
characterized for the symmetric case. The exact capacity region of this
channel is also established if the channel vectors satisfy certain
constraints.
