Enhanced pilot signal receiver

Abstract

Briefly, in accordance with one embodiment, a method of adjusting for digital automatic gain control (DAGC) quantization error in a mobile station is as follows. A first DAGC value is stored before reception of one or more enhanced pilot signals. A second DAGC value is computed during reception of the one or more enhanced pilot signal. The first DAGC value is restored after reception of the one or more enhanced pilot signals is over. An advantage associated with this particular embodiment may include reduction in quantization error for digital automatic gain control.

1 . A method of adjusting for digital automatic gain control (DAGC) quantization error in a mobile station:
 storing a first DAGC value before reception of one or more enhanced pilot signals;   computing a second DAGC value during reception of the one or more enhanced pilot signal; and   restoring the first DAGC value after reception of the one or more enhanced pilot signals is over.   
     
     
         2 . The method of  claim 1 , wherein, for more than one received enhanced pilot signals, the enhanced pilot signals are mutually orthogonal along at least one of the following signal dimensions: time, frequency, or any combination thereof. 
     
     
         3 . The method of  claim 2 , wherein the one or more enhanced pilot signals are compatible with at least one of the following signaling protocols: 1x EV-DO; cdma2000; WiMAX; LTE; or UMB. 
     
     
         4 . The method of  claim 1 , and further comprising: selecting a portion of an analog-to-digital converted (ADC) value as a DAGC value for the first and second DAGC values. 
     
     
         5 . An article comprising: a storage medium having stored thereon instructions that if executed direct a mobile station to store a first DAGC value before reception of one or more enhanced pilot signals, compute a second DAGC value during reception of the one or more enhanced pilot signal, and restore the first DAGC value after reception of the one or more enhanced pilot signals is over. 
     
     
         6 . The article of  claim 5 , wherein, for more than one received enhanced pilot signals, the enhanced pilot signals are to be mutually orthogonal along at least one of the following signal dimensions: time, frequency, or any combination thereof. 
     
     
         7 . A mobile station comprising: a computing platform; said computing platform to store a first DAGC value before reception of one or more enhanced pilot signals, compute a second DAGC value during reception of the one or more enhanced pilot signal, and restore the first DAGC value after reception of the one or more enhanced pilot signals is over. 
     
     
         8 . The mobile of  claim 7 , wherein, for more than one received enhanced pilot signals, the enhanced pilot signals are to be mutually orthogonal along at least one of the following signal dimensions: time, frequency, or any combination thereof. 
     
     
         9 . A mobile station comprising:
 means for storing a first DAGC value before reception of one or more enhanced pilot signals;   means for computing a second DAGC value during reception of the one or more enhanced pilot signal; and   means for restoring the first DAGC value after reception of the one or more enhanced pilot signals is over.   
     
     
         10 . The mobile of  claim 9 , wherein, for more than one received enhanced pilot signals, the enhanced pilot signals are mutually orthogonal along at least one of the following signal dimensions: time, frequency, or any combination thereof.
