Introduction To setup the coefficients for both uplink and downlink, the technique described here is applicable. The differences are in the upper/lower bound of the frequency response as described in the 3GPP standards (3GPP TS 51.010). . Compression The compression must be set up to be EFR (Extended Full Rate). Equipment A CMU200 with a UPL16 is to be assumed in this case. Matlab as a tool will also be required. The CMU200 and UPL16 are to be set for Acoustic testing. IIR Description The IIR Filter developed by Agere is composed of 3 Bi Quads with a gain Stage. This filter is defined in the tcconfig.c file together with the gain. Each Bi Quad has 6 coefficients associated with it although one is fixed. Therefore, each Bi-Quad has 5 coefficients to be set. The IIR filter……
