BER Calculator (beta)

by Jos Akhtman

The following tool is capable of predicting the achievable Bit Error Rate (BER) performance exhibited by a wide range of wireless transceiver schemes. The estimated BER performance is calculated using a semi-analytical model. The model employed is particularly accurate for uncoded systems, where it may be regarded as fully analytical. In the case of coded systems the model is designed to approximate the performance of the particular transceiver scheme employed by the authors. More specifically, we used a parallel-concatenated turbo-coded system.

Key:

M: Rectangular M-QAM constellation type; coded: Channel encoding scheme [0 - none, 1 - rate 1/2 turbo]; it: No. channel code decoding iterations; ray: Channel fading type [0 - none (AWGN channel), 1 - Rayleigh fading]; B: Signal bandwidth [MHz]; T: Interleaver depth [symbols]; fD: Doppler frequency [Hz]; trms: RMS delay spread [μsec]; mt: No. transmitters; nr: No. receivers;

SNR: Signal to Noise Ratio - the ration between the total signal power and the AWGN power recorded at each receive antenna;
E_b/N₀: Energy per bit to Noise ratio - the ration between the energy per transmitted information bit and the the average energy of AWGN sample recorded at each receive antenna;
