Abstract This paper presents a novel memory optimization technique to exploit the analogy
between correlation coefficients in MMSE-based channel estimators across multiple
standards. The need for coefficient storage for robust MMSE channel estimators is

Abstract Vehicle-to-vehicle (V2V) communications have seen growing attention in the last
few years. In this work, we address the use of the 3GPP Long Term Evolution (LTE) standard
technology applied to V2V. We employ empirical models for the V2V channel, and show

Abstract This paper proposes and proves a theorem which stipulates sufficient conditions
the coefficients of two quadratic permutation polynomials (QPP) must satisfy, so that the
permutations generated by them are identical. The result is used to reduce the search time

Since the days of analog mobile phones, NTT DOCOMO has made a great effort to improve
reception in indoor dead areas in order to expand the indoor service area as much as the
outdoor service area. Various types of equipment have been developed and installed to

NTT DOCOMO began operation of the LTE system in Tokyo, Nagoya and Osaka regions in
December 2010. This system uses 3G frequency bands, providing high-speed data
downlink at 100 Mbit/s or greater and uplink at 50 Mbit/s or greater, and provides

Abstract Handover parameter optimization is a selfoptimizing network (SON) use case that
promises significant performance improvement of the radio network. The basic idea is to
adapt the handover control parameters, hysteresis and time-to-trigger, to the individual
