Millimeter Wave/ 5G Channel Simulator NYUSIM Version 1.6.1

Dear NYUSIM users,

Thank you for your interest in our open-source Millimeter Wave/ 5G Channel Simulator NYUSIM. You are receiving this email because you have previously downloaded NYUSIM and entered your email address into our database.

We would like to announce that a new version (Version 1.6.1) of NYUSIM has just been released and is available at nyuwireless.com/nyusim. Version 1.6.1 provides two major improvements to NYUSIM, based on user feedback. The first improvement provides a complete MIMO channel representation. The second improvement fixes a crash when the RF bandwidth is set to be smaller than 800 MHz.

• (a) Fix 1: In Version 1.6 and earlier versions, NYUSIM only used the first TX antenna element with all RX antenna elements to generate the MIMO channel impulse responses, where NYUSIM should have used all TX antenna elements (N_TX) with all RX antenna elements (N_RX) when producing the MIMO channel impulse responses. In other words, earlier versions of NYUSIM only generated 1 x N_RXcomplex voltages for a particular multipath component. However, for proper MIMO channel modeling, N_TX x N_RX complex voltages of a particular multipath component are needed. The MIMO channel function is improved to generate a full MIMO impulse response (channel matrix) with respect to the number of TX antennas and the number of RX antennas. The parameter "CIR_MIMO" is expanded for all TX antenna elements for actual MIMO implementations and adjusted according to the user-specific RF bandwidth.
• Fix 2: In Version 1.6, a bug occurs when the RF bandwidth is set to be less than 800 MHz. The time resolution of the system becomes more coarse as the bandwidth is set by the user to be narrower than 800 MHz. Thus, fewer multipath components can be resolved at narrower bandwidth compared to the 800 MHz bandwidth. Thus, multipath components that arrive within a time bin are vectorially summed, and the function "getNewPowerSpectrum.m" in v 1.6.1 will correctly generate the band-adjusted power spectrum. AOA and AOD information retain 800 MHz bandwidth resolution, even if the user decreases the RF bandwidth.

More details about Version 1.6.1 can be found on the NYUSIM website (nyuwireless.com/nyusim) and in the NYUSIM user manual.

Please feel free to download and use NYUSIM v1.6 if interested. Thank you again for your interest and support!
