We consider a slotted broadcast channel,and Poisson user model.We then propose and analyze a limited feedback sensing algorithm,for collision versus noncolilsion binary feedback.The algorithm has throughput equal to .42,it has uniformly good delay characteristics within its stabilityregion,and it is robust in the presence of feedback errors.A variation of the algorithm,for ternary feedback,attains throughput .425,and it has uniformly good delay characteristics within its stability region. In contrast,the highest throughput limited feedback sensing algorithm existing,for ternary feedback [1],attains throughput .456,but it induces relatively high delays,for Poisson intensities below .3.
