Frame Error Rate (FER) measurement is used to test the performance of a mobile station's receiver. FER measurements can only be made on the forward frame error rate in gsm traffic channel (F-Traffic) for IS-95 system or forward fundamental channel (F-FCH) for IS-2000 system and

a call must be connected with a loopback service option (such as SO2, SO9, SO55 or SO75). The forward supplemental channel (F-SCH) for frame error rate wikipedia IS-2000 system is measured using TDSO FER measurement (see TDSO Frame Error Rate Measurement Description ). During an FER measurement, the test set sends a sequence of frames to the mobile station. Each frame contains CRC (Cyclic Redundancy

Code) bits, which provide frame quality indicator and allow the mobile station to verify that it has correctly decoded a frame. The mobile station is put into a loopback service option and makes its best attempt to decode each received frame sent from the test set. Once the mobile station determines the CAT_TYPE that specifies whether the frame received is a good frame, bad frame, frame erasure, or a frame blanked by signaling, the mobile station encodes frame erasure rate wikipedia and re-transmits the frame, with the first two bits replaced with the CAT_TYPE information, back to the test set. The test set compares each received frame to the corresponding frame that was sent and validates the CAT_TYPE information, then determines the measurement results (see FER Measurement Results ). The test set keeps a running count of the measured frames and the number of frames that contain bit errors. Intermediate measurement results are periodically available on the front panel display, but are not available programmatically through the GPIB interface. Confidence Level Testing Confidence level testing is a feature of FER measurements that applies statistical analysis to FER measurements so that pass/fail test results can be obtained in the shortest possible time. When confidence level is on, a minimum number of frames as specified must be measured before confidence algorithm can begin (For fading tests, the minimum test duration is required to meet the power measurement uncertainty requirement of 0.2 dB). After the measurement is initiated and the specified minimum frames have been tested, given an FER requirement and confidence level settings, a calculation is made to determine the minimum number of remaining frames necessary for a valid statistical analysis. At that time it is also determined what the maximum number of bad frames received would be necessary to fail the test. If the pre-calculated maximum number of bad

& FER? I want to send bit streams in frames and then calculate the channel capacity. I want the capacity in general form not only for AWGN channels. https://www.researchgate.net/post/What_is_the_relationship_between_Channel_capacity_FER I wrote the codes for calculating FER and BER in matlab, then I simulated it for different modulations (Bpsk,Qpsk, 8Psk) but now I want to calculate the channel capacity and through put, and I was looking for a specific formula between BER,FER ,PER and capacity. I found these two formula: 1- C = W*log2(1 + BER_gap*SNR); (as Talha Faizur Rahman mentioned error rate it ) 2- C = (Nd* Nb*Rfec*Rstc/Ts)* (1-PER) (in this paper http://arxiv.org/abs/1002.1954) but still I am looking for a way to calculate C from FER. I think it shoul be something like : C = Nominal-Rate (1- FER) but I don't know which parameters should be considered in the nominal rate Topics Wireless Communications × 960 Questions 31,402 Followers Follow May 28, frame error rate 2014·Modified May 28, 2014 by the commenter. Share Facebook Twitter LinkedIn Google+ 1 / 0 Popular Answers Abdelhalim Zekry · Ain Shams University Dear Sadaf, The channel capacity by definition is the maximum bit rate that can be transmitted across the channel with a specific bit error ratio. So if you have the frame error rate ref, i.e., the ratio of frames in error to the total number of frames ref, you can calculate bit error rate reb by just dividing the frame error rate ref by the number of bits per frame Nf assuming one bit error in the frame on the average. That is reb= ref / Nf for one bit error in the frame on the average. Then you can calculate the ref max allowed= reb max allowed x Nf So you start with small frame rates and increase it gradually while observing the frame error rate till it becomes equal than the maximum allowed frame error rate rf max allowed. This is then the channel capacity in frames per seconds. You can get the maximum bit error rate which i
