2 Overview

Overview
2.1 Introduction In a wireless communications system, multipath propagation is the phenomenon that results in radio signals reaching the receiving antenna by two or more paths. Multipath propagation causes the amplitude, phase, and angle of receive (RX) signals to fluctuate, which is known as multipath fading. It deteriorates the quality of RX signals. As one of the technologies applied to counteract multipath fading, the diversity technology in the GSM system consists of time diversity, frequency diversity, and space diversity. With space diversity, two or more antennas are used at the RX end to receive signals from the same source. The RX signals are then processed and combined to minimize the impact of multipath fading. This document describes the technology that enables a BTS to use two antennas (or two polarization ends of the same polarization antenna) to receive signals from the same source. The technology is implemented by the 2-Antenna Receive Diversity feature.
2.2 Benefits The 2-Antenna Receive Diversity feature improves uplink receive quality, receiver sensitivity, and uplink coverage for BTSs. As this feature does not require additional hardware installation or algorithm implementation, it reduces the capital expenditure (CAPEX) for telecom operators.

3 Technical Description
Technical Description
The 2-Antenna Receive Diversity feature combines the signals from the same source received by two diversity antennas to counteract multipath interference. Figure 3-1 shows the implementation of 2-Antenna Receive Diversity. Figure 3-1 Working principle of 2-antenna receive diversity
As shown in Figure 3-1, 2-Antenna Receive Diversity is implemented as follows: 1.
The signal x(k) arrives at diversity antennas over two RX channels, and the two signals transmitted over these RX channels are identified as r1(k) and r2(k). After being superimposed on interferences and noises, the two signals are identified as S1(k) and S2 (k).
2.
According to its own criterion, the MRC, ICC, EICC, or MICC algorithm calculates the combining coefficients W1 and W2 and obtains the output signal y(k) using the following formula: y(k) = W1 x S1(k) + W2 x S2(k) NOTE
l In Figure 3-1, RX channels 1 and 2 correspond to the main diversity RX channels of a TRX board. l 2-Antenna Receive Diversity supports four diversity combination algorithms: MRC, ICC, EICC, and MICC. Each of them has its own combining coefficients W1 and W2.
The 2-Antenna Receive Diversity feature is enabled by setting RCVMD (BSC6900,BSC6910,eGBTS) to MAINDIVERSITY(Main Diversity) and configuring two receive antennas for each related device. When you configure receive antennas, ensure that the following conditions are met: Issue Draft A (2014-01-23)

l
For a GBTS, the connection mode between RF modules and antennas is set to the two-way receive mode by setting SndRcvMode(BSC6900,BSC6910),SndRcvMode1 (BSC6900,BSC6910), SndRcvMode2(BSC6900,BSC6910), and SndRcvMode3 (BSC6900,BSC6910). Additionally, the connection mode of antennas is consistent with the actual connections.
l
For an eGBTS, two receive antennas are configured by setting ANTNUM. The send and receive mode of the two receive antennas is set to RX_MODE(RX) by setting ANTTYPE1 and ANTTYPE2. NOTE
When the value of ANTNUM (the maximum value is 8) is greater than 2, set all the following parameters for each antenna: ANTTYPE1, ANTTYPE2, ANTTYPE3, ANTTYPE4, ANTTYPE5, ANTTYPE6, ANTTYPE7, and ANTTYPE8.
The MRC, ICC, EICC, and MICC algorithms estimate noises or suppress interferences in different ways. Therefore, the quality of output signals differs for each algorithm. For details about these algorithms, see Interference Cancellation Combining Feature Parameter Description.
