Introduction

Introduction

BINARY MODULATION

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

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

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

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.
