### Orthogonal Frequency Division Multiplexing (OFDM)

Orthogonal Frequency Division Multiplex (OFDM) Tutorial 5 In OFDM we have N carriers, N can be anywhere from 16 to 1024 in present technology and depends on the environment in which the system will be used.

### Orthogonal Projections

Reections and Projections Notice in Figure 2 that the projection ofvinto Wis the midpoint of the vectorvandits reectionHv=Re W (v); that is, Qv= 1 2 (v+Hv) or, equivalently Hv=2 Qvv; whereQ=Q W denotes the projection onto W.

### Linearly Independent, Orthogonal, and Uncorrelated Variables

Linearly Independent, Orthogonal, and Uncorrelated Variables JOSEPH LEE RODGERS, W. ALAN NICEWANDER, and LARRY TOOTHAKER* Linearly independent, orthogonal, and uncorrelated are three terms used to indicate lack of relationship between variables.

### Topic 4. Orthogonal contrasts

1 Topic 4. Orthogonal contrasts [ST&D 183] ANOVA is a useful and powerful tool to compare several treatment means. In comparing t treatments, the null hypothesis tested is that the t true means are all equal (H 0: + 1 = + 2 = ... = + t).
