A new simulation model for non-stationary fading channel

A Novel Simulation Model for Nonstationary Rice Fading Channels

“…To overcome this shortcoming, a new method, namely, sum of frequency modulation signals [12,[15][16][17][18] or sum of chirp signals [19], was proposed to simulate nonstationary Rayleigh channels very recently, but it lacked implementation details and performance analyses. To fill this gap, this paper develops a new simulator based on this idea to generate the nonstationary Rice fading channels under nonisotropic scattering scenarios, as well as the upgraded computation methods of simulation parameters.…”

“…However, measurement campaigns have proved that the WSS assumption is only valid for a short time interval [20]. Therefore, several modified SoC-based simulators were proposed in [9][10][11][12][13][14][15][16][17][18][19] to generate nonstationary fading channels. For example, the WINNER+ model [9] was simulated by generating several independent channel segments with different simulation parameters.…”

“…There are a number of research papers on designing accurate and efficient simulators [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. For the good fitting with plan-wave propagation channels, the sum-of-sinusoids (SoS) [1,2] or sum-ofcisoids (SoC) [3] based simulators and their derivatives [4][5][6][7][8] have gained the most widespread acceptance.…”
