A Carrier Phase Acquisition Scheme for TC-QAM System

open access: yes工程科学与技术, 2006
:An all-digital carrier phase acquisition scheme was presented to solve the problem of carrier phase recovery, which is specially critical and hard in the demodulation of trellis coded quadrature amplitude modulation (TC-QAM).

Trellis coded modulation techniques [PDF]

open access: yes
The subject of this thesis is an investigation of various trellis coded modulation (TCM) techniques that have potential for out-performing conventional methods. The primary advantage of TCM over modulation schemes employing traditional error-correction coding is the ability to achieve increased power efficiency without the normal expansion of bandwidth
