Publication Description :

The  demand  for high-speed  mobile  wireless  communication  is  rapidly  growing.   Minimum  Shift Keying  (MSK)  based  modulation  technology  can  be  used  for  achieving   high accuracy data transmission and for high data capacity. Phase Shift Keying (PSK)   is  used  for  MSK  and  Gaussian  Minimum  Shift  Keying  (GMSK).  In  this  paper,  we   consider  only  MSK  based  signal  and  two  channels;  Additive  White Gaussian  Noise   (AWGN)  channel  and  Rician  fading  channel. MSK  based  modulated  signals  transmit   through the AWGN channel with varying Signal to Noise Ratio (SNR) and signal power.   Also  MSK  based  modulated  signals  transmit  through  Rician  fading  channel  with   varying  Doppler  shift  (fd)  and  the Rician  K-factor.  We  analyze  the  properties  of  MSK   based  transmitted  signal  for  each  varying  factors  in  both  AWGN  and  Rician  fading   channel. A comparison has been made between the  MSK based signal through AWGN   and  the  MSK  based  signal  through  Rician  fading  channel.  Finally,  we  investigate  the   BER  performance  of  the  MSK - based  system  for  AWGN  channel  and  Rician  fading   channel. Here, we propose that the AWGN channel is better than Rician fading channel   for transmitting the MSK based modulated signal.
