“…The paper reports 4 to 22 times improvement compared to uncoordinated transmissions in the two cells. The paper [10] presents similar real-time implementations and reports 2.6 times gain over uncoordinated cells (see Table II of [10]). The paper [11], reports 31% and 55.3% gains over uncoordinated cells.…”

We have implemented interference alignment (IA) and joint transmission coordinated multipoint (CoMP) on a wireless testbed using the feedback compression scheme of the new 802.11ac standard. The performance as a function of the frequency domain granularity is assessed. Realistic throughput gains are obtained by probing each spatial modulation stream with ten different coding and modulation schemes. The gain of IA and CoMP over TDMA MIMO is found to be 26% and 71%, respectively under stationary conditions. In our dense indoor office deployment, the frequency domain granularity of the feedback can be reduced down to every 8th subcarrier (2.5MHz), without sacrificing performance.
