Abstract: A multi-class multimedia broadcast/multicast service (MBMS) system includes a transmitter and at least one receiver. The transmitter transmits N primary signals by N primary channels and an auxiliary signal by an auxiliary channel, wherein a resolution of the auxiliary signal is identical to the highest resolution of the N primary signals and the constellation mappings of the auxiliary signal and the primary signal with the highest resolution among said N primary signals on the corresponding modulation constellations are coupled. The receiver couples the primary signal with the corresponding auxiliary/virtual auxiliary signal to obtain a lower-resolution virtual auxiliary signal, which can also be coupled with the primary signal having the same resolution. Therefore, receiving quality of each resolution is improved by combining the primary signal and the corresponding auxiliary/virtual auxiliary signal.

Abstract: A communication method of coordinated multi-point transmission systems. Based on the Zadoff-Chu sequences, multiple training sequences are implemented, and the training sequences are a set of robust orthogonal training sequence (ROTS). Preamble signals that use the set of training sequences can be transmitted from multiple base stations/relay stations at the same time. In the case with the mixture signal of multiple preamble signals, user equipment can still use the received signal to estimate multiple carrier frequency offsets of the corresponding base stations/relay stations.

Abstract: A communication method for estimating Doppler spread includes the following steps: transmitting a preamble signal to a receiver from a transmitter of a transmission terminal. The preamble signal is received by the receiver; followed by dividing the received samples in the preamble signal into a plurality of sets of samples. The plurality of sets of samples are introduced into a Doppler spread estimation algorithm to estimate Doppler spread.
