88 / 136 page ![]() 1996 Oct 29 88 Philips Semiconductors Objective specification GSM signal processing IC PCF5083 9.3.2 PERFORMANCE OF GSM BASEBAND PROCEDURES The performance of the PCF5083 GSM baseband procedures is specified within this section. All performances are valid for the following conditions; unless otherwise specified. However, performance figures are only preliminary or must be fixed respectively. • AGC and quantization in accordance with Fig.16 • Receiver input noise (AWGN); −111 dBm • IF filter with a frequency characteristic as shown in Fig.20 • Constant frequency offset (df) in baseband signal; −100 Hz ≤ df ≤ 100 Hz • Gain mismatch in I and Q path less than 0.5 dB • Phase error less than 2° • Channel models in accordance with “GSM Rec. 05.05”. 9.3.2.1 Usable receiver input level range Table 63 Usable receiver input level range SYMBOL PARAMETER CONDITION MAX. UNIT NER1 nominal error rate; TCH/FS class II static; −10 dBm 2 × 10−5 − NER2 nominal error rate; TCH/FS class II static; −50 dBm 2 × 10−5 − NER3 nominal error rate; TCH/FS class II static; −85 dBm 2 × 10−5 − NER4 nominal error rate; TCH/FS class II EQ50; −40 dBm 2.5 % NER5 nominal error rate; TCH/FS class II EQ50; −85 dBm 2.5 % Fig.20 Frequency response of the IF filter. handbook, halfpage 0 500 0 −100 −80 −60 −40 −20 MGE298 100 200 300 400 gain (dB) frequency (kHz) |
