Therefore the average transmission rate of BPSK is given by:
En la figura 13 se puede observar que los valores mas altos a nivel del BER se establecen para un valor nominal de radio SNR igual a 4 dB; la razon para la presencia de un alto BER son dos: la primera es que este se encuentra en el sector de mas baja relacion senal a ruido (canal en las peores condiciones en presencia de ruido), y la segunda y mas representativa es que se presentan errores de interpretacion al estar conmutando entre los margenes de cambio de modulacion BPSK y QPSK, de acuerdo con los valores de SNR segun la distribucion aleatoria gaussiana (AWGN) (ver la tabla 3).
The BPSK Baseband Modulator block modulates a signal using the binary phase shift keying method.
Dependence of error probability for a BPSK modulation scheme on free space path loss in the uplink and the downlink: dots indicate values without coding, circles--with convolutional coding (rate 3/4, constraint length K = 7); 20 K noise temperatures of satellite and ground receivers are indicated by dashed lines and 290 K by solid lines; HPAs back-off level is 7 dB; phase and frequency offsets are equal to zero, [d.
The BER values have been computed as a function of SNR for PSK modulation in terms of BPSK and QPSK modulation and different combinations of MIMO systems using MMSE, MMSE-SIC, Modified MMSE, ML and ZF, ZF-SIC, ZF-SIC-Sort equalizers.
As stated before, much research effort is done to maximize the benefits of turbo codes applied on BPSK signals.
11a/g features are supported including data scrambling, forward error-correction via convolutional encoding at rates from 1/2 to 3/4, sub-channel coding of BPSK, QPSK, 16QAM or 64QAM, both short- and long-training sequences, pilot insertion, and the IFFT/FFT required to convert to/from time-domain RF I/Q signals.
Much like our previous hypothetical FM signal example, all frequency content of the BPSK signal is affected by Doppler as well.
According to Sklar (Sklar, 2002), turbo codes were first introduced in 1993 by Berrou, Glavieux, and Thitimjshima achieving a bit-error probability of 10-5 using a rate 1/2 code over an additive white Gaussian noise channel and BPSK modulation at an [E.
Por lo cual tenemos BPSK con 2 fases (equivalente a PAM), QPSK con 4 fases (equivalente a QAM), 8-PSK con 8 fases y asi sucesivamente.
