Figure 292: CDMA Link level data library elements

Regarding the library sets of CDMA Link level data, the default sets distributed within SEAMCAT library are understood to be sufficient to cover typical CDMA systems expected to be deployed in Europe and their respective frequency bands. You may defined any Any additional link level data may be defined to cover other types of CDMA systems. However, it is recommended that only users with advanced knowledge of CDMA systems develop the new CDMA Link level data for SEAMCAT simulations as several serious considerations should be undertaken before kept in mind  before creating new Link level data: 

• • The SEAMCAT CDMA Link level data have different formats for uplink and downlink sections of CDMA link. In particular, the Link level data for uplink provides Eb / No requirements, whereas downlink data define the Ec / Ior requirements;
You should check
• • Check carefully that the newly created CDMA link level data is appropriate for the SEAMCAT's CDMA simulation methodology for the respective section of the link (uplink/downlink).
