Abstract :
Cellular TDMA-based handsets for the PCS 1900 MHz band will soon become very popular. With the cellular band at 900 MHz being congested by too many users the new band offers the service to twice as many customers. However, the requirements on the symbol recovery become much harder since a Doppler speed twice as high as in the cellular band is expected. Further impairment is given by the hardware realization that introduces timing errors and frequency offsets. This paper describes a Viterbi based equalizer-scheme that performs well under these conditions and satisfies the standards for cellular phones.
