Methods of controlling a transmission power and configuring a codebook in a multi-antenna system to solve a transmission power unbalance between antennas are disclosed. The method of transmitting data in a multi-antenna system includes (A) transmitting one or more pilot signals within a first symbol region through a first antenna unit, and (B) transmitting one or more pilot signals within a second symbol region through a second antenna unit, wherein data within the first symbol region is transmitted through the second antenna unit, and data within the second symbol region is transmitted through the first antenna unit. According to the present invention, since a transmission power unbalance between antennas is solved, a transmission power can be uniformly assigned to each antenna and channel estimation can be easily performed. Moreover, a power amplifier having a uniform amplification range can be used and designed.

The present invention relates to a new use of Hades as a tumor suppressor target, more particularly to a composition for suppressing tumor comprising an expression or action inhibitor of Hades protein having an amino acid sequence of SEQ ID NO: 2 as an effective ingredient. The present inventors have found that the overexpressed Hades protein interacts with p53 to inhibit the exonuclear mechanism of p53 and the knowdown of Hades induces increase in the expression of p53, demonstrating that Hades is a negative regulator to p53. Therefore, it would be understood that the inhibition of Hades overexpressed in tumor cells contributes to tumor-supressive effects of p53. The drug candidates capable of modulating the expression of the Hades protein, inhibiting the actions of the Hades protein or inhibiting interecation between Hades and p53 are considered a promising anticancer drug.

A method of transmitting data using a generalized phase shift based precoding or an extended phase shift precoding scheme in a multiple-antenna system using a plurality of subcarrier and a transceiver for supporting the same are disclosed. A phase shift based precoding matrix may be generalized and determined by a product of a diagonal matrix for phase shift and a unitary matrix for maintaining orthogonality in spatial domain. The diagonal matrix may be extended by a product of a precoding matrix for increasing channel power and the diagonal matrix for phase shift. The design of the transceiver can be simplified or communication efficiency can be improved by generalizing and extending the phase shift based precoding.

A feedback method for a multi-antenna system is disclosed. The feedback method for use in the multi-antenna system can reduce an amount of transmission (Tx) feedback information associated with a precoding matrix (i.e., a codebook). For example, a single codebook may include precoding matrixes associated with several ranks. A basic matrix constructing the precoding matrix is extended to a frequency axis, such that it can be used as a Cyclic Delay Diversity (CDD) structure.
