Radio Reception
32 Radio Reception
Radio reception defines the function to receive an RF signal from the
air interface and restore the bit stream. Diversity is used to improve the
sensitivity on the receiver. It is achieved by having two antennas, and
by that means take advantage of two or more receiver paths.

32.2 Radio Reception
Purpose
To receive an RF signal and restore the bit stream that constitutes a
burst.
Precondition and initiation
The ATSR must be in traffic. The reception initiates when the ATSR is
taken into traffic.
Description
The RBS receives an RF signal from the MS on the air interface. First
the signal is filtered in order to isolate the targeted MS signal from other
transmission. Then the signal is amplified and finally demodulated. In
the demodulation phase the bit stream that constitutes a burst is restored.
The GSM 900 specification of Receiver characteristics is found in /
GSM 05.04/ and /GSM 05.05/.
The GSM 1900 specification of Receiver characteristics is found in /
PCS 4/, /PCS 5/ and /PCS 6/.
32.3 Diversity
Purpose
To improve sensitivity on received signal.
