Abstract

The end-to-end bit-error performance of 64-QAM transmission using a hybrid fiber-coax system test bed designed for delivery of 77 AM-VSB and 25 64-QAM video channels covering the frequency band 54 - 702 MHz was studied. Error-free QAM transmission was achieved with the use of modulated analog carriers and Reed-Solomon (204, 188) error-correction coding indicating that in hybrid fiber-coax systems transport of AM-VSB and 64-QAM signals can be realized maintaining both analog and digital performance requirements.
