SIGNATURE SEQUENCE SELECTION, SYSTEM VALUE BIT LOADING AND ENERGY ALLOCATION METHOD AND APPARATUS FOR MULTICODE SINGLE- INPUT SINGLE - OUTPUT AND MULTIPLE- INPUT MULTIPLE - OUTPUT PARALLEL CHANNELS

摘要

A method of transmitting data over a radio data transmission system having a plurality of K parallel single-input single-output or multiple-input multiple-output channels, the method comprising transmitting data at a rate b_p+1 bits per symbol over a first group of (K- m) channels, and at a rate 6, bits per symbol over a second group of m channels, by spreading the data using a number of signature sequences.
