8. BINARY MODULATION

9. M-ARY MODULATION
To use M-ary modulation, the bit stream is blocked into groups of λ bits.
The number of bit patterns is M = 2λ

10. M-PSK MODULATION
In this modulation type, the information is encoded in the phase of the transmitted signal.

11. 64-PSK MODULATION
The signals lie on a circle of radius √Es, and are spaced every 2π/M radians around the circle.

13. BIT ERROR RATE
The bit error rate or bit error ratio (BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval.
Bit error rate (BER) is a parameter which gives an excellent indication of the performance of a data link.

14. Theorethical BER of 64-PSK
k=log2M
k=log2(64)
k=6bits

15. Results

16. CONCLUSION BPSK has following specification such as: High data rate
High power efficiency (minimum required transmit power)
Low cost implementation

17. CONCLUSION
Bandwidth and Power Efficiency of M-PSK Signals
