Resolution Bandwidth (1xEV-DO)

Resolution bandwidth (ResBW) in 1xEV-DO demodulation is determined automatically by the VSA, and cannot be set independently. Resolution bandwidth is determined by the time record length according to the following formula:

However, in 1xEV-DO Demodulation the time record length is determined as follows (result length is in symbols):
