Non-uniform QAM constellations with constellation points at positions of maximum capacity for a selected signal to noise ratio |
| abstract |
A method and transmitter and receiver for determining and transmitting or receiving a non-Âuniform QAM signal comprises selecting a signal to noise ratio (SNR) for a channel and forward error corrector and then determining positions of constellation points that maximize a measure of channel capacity at the selected signal to noise ratio. The position of one constellation point and another constellation point within the constellation are constrained to be equal to one another prior to determining the positions of the constellation points. In doing so, a so called condensed QAM constellation arrangement may be derived having fewer than conventional number of constellation points for a given QAM scheme. |
