Subject:              Results of Processing Gain Tests for FCC Qualification



1          INTRODUCTION


This memo presents the results of the Processing Gain (PG) tests carried out for FCC
qualification of the Cambridge Silicon Radio BC01B Bluetooth chip. The FCC states that the
PG from a hybrid Bluetooth receiver must be greater than 17 dB when measured in
accordance with the Continuous Wave (CW) jamming margin method. Testing of the BC01b
has found the PG due to the DS section to be approximately 5 dB and the PG due to the FH
part to be approximately 15 dB. It is therefore concluded that the BC01B complies with the
FCC PG requirements for radio communication systems.


The rest of this paper outlines the PG measurement technique and discusses the test results.
Appendix A contains a list of test equipment and Appendix B contains a printout of the
measurement results.



2          METHOD

2.1        PG Definition
The Processing Gain from a frequency hopping communication system is derived from two
parts, the FH section and the DS section. The PG due to FH is given by a simple equation and
is constant. However measurement of the PG due to DS is a little more complex. One
technique is to use the CW jamming margin method. This method measures PG due to DS
using the following algorithm:


A CW signal generator is stepped in 50kHz increments across the passband of the system,
recording at each point the generator level required to produce the 0.1% Packet Error Rate
(PER). This is the jammer level. This level is then referenced to the output power of the
intended Bluetooth signal and the Jammer to Signal Ratio JSR is thus calculated. The worst 4

                                                                             Page 2 of 11
                                                                              PG Results
                                                                           23 March 2001


JSR measurements are discarded and the worst remaining JSR is used to calculate the PG
due to DS as follows:
                                  G p = SNR +JSRmin + Lsys

where Gp = the processing gain of the system, SNR = the signal to noise ratio required for
0.1% BER, JSRmin = minimum J/S ratio and Lsys = system losses.



2.2     PG Measurement Technique
Figure 1 provides an overview of the PG measurement technique. The measurement is
performed in two parts, measurement of the system SNR and measurement of JSRmin.




                         Figure 1: PG Measurement Technique


The system SNR is calculated using the following algorithm. Generate Bluetooth PRBS-9
packets using a BC01B emulator (1) and a Vector Signal Generator (2). Combine this signal
with white noise of a constant level, which is generated using a noise source (4) and a CW
Signal Generator (3). Then vary the level of the Bluetooth signal until the BER measured by
the BC01B (7) is 0.1%. The resulting SNR is the signal level divided by the Noise level.

                                                                              23 March 2001


The JSR for a given jamming frequency is calculated using the following algorithm. Generate
Bluetooth PRBS-9 packets using the BC01B emulator (1) and the Vector Signal Generator
(2). Combine this signal with a constant CW tone at the jamming frequency using a CW
Signal Generator (5) and a combiner (6). Then vary the level of the Bluetooth signal until the
PER measured by the Casira Bluetooth Module (7) is 0.1%. The resulting JSR is the signal
level divided by the jamming level.



3        RESULTS

3.1      Overview
The measurements found that the PG due to DS caused by the access code in page and
inquiry mode is found to be approximately 5dB when the access code is a relatively random
mixture of 1's and 0's. A random access code causes the most Inter Symbol Interference (ISI)
and hence the worst PG for a hybrid system. Therefore only the results for this access code
are used in the PG calculation.


The PG due to FH is given as
                        PGFH = 10 log10 (number of frequency hops)
The number of hops in a Bluetooth system is 32, therefore the PG due to FH is approximately
15 dB. When this is added to the PG due to DS, the total PG for the BC01B is approximately
20 dB, above the minimum PG requirement for FCC qualification.

To calculate processing gain, ignore the worst 20% of data points and then apply the
following formula:


                                                                                                   Page 4 of 11
                                                                                                    PG Results
                                                                                                 23 March 2001



                                              G p = SNR +JSRmin + Lsys

Where                  Gp             = Processing Gain of the module
                       SNR            = signal to noise ratio of the module
                       JSmin          = minimum J/S ratio after the worst 20% of J/S samples have been
                                        discarded
                       Lsys           = System losses

A total of 20 samples were taken by stepping the jamming signal frequency offsets in 50kHz
increments over the bandwidth of the receiver. The worst 4 samples were found at –500kHz,
-450kHz, -400kHz and 500kHz and were discarded. The remaining minimum J/S ratio was
found to be -15.4dB at an offset of +350kHz

Thus, the processing gain due to direct sequence spreading in page and inquiry mode is
                                          G p = 18.8 − 15.4 + 2 = 5.4dB
