gsm_phdEqualization in GSM using a priori information Master of Science Thesisby Anders Jarl April 1998Examiner: Prof. Bjrn OtterstenSupervisors: Stefan Hkansson, LRU/BT Johan Backman, LRU/BT Martin Kristensson, KTH AbstractThis thesis describes a method to improve the estimate of the channel impulse response that is calculated in the GSM receiver. The estimation is today performed of a concatenated net channel that includes the known transmit and receive filters. The new method exploits this a priori information about the channel in the estimation process. The inclusion of the a priori information leads to new constraints that the channel estimate must satisfy. The new method shows that good results can be achieved if the constraints are fulfilled and if the channel is not time dispers……
