Different from movies or books in conventional recommendation problem, events usually have recommendation lifetimes and almost all the events to be recommended are upcoming, which brings a severe cold start problem.

In this paper, a phase noise cancellation (PNC) architecture is presented for 60 GHz communication systems. The BER performance is severely degraded by the non-ideal carrier frequency in 60 GHz bandwidth, which causes both common phase error (CPE) and residual carrier frequency offset (RCFO). The proposed simplified two-stage CPE algorithm solves the RCFO and common phase nose in the frequency domain...
