QPSK Modulation for CDMA

If the modulation data changes, QPSK modulation makes one symbol change each period. If the data is the same, then QPSK and OQPSK do not change state. However, if the

List of CDMA Service Options

A number of different service options have been defined for use on the CDMA physical channel. A description of each of the service options follows: Service Option 001 – This

Sectorization Gain in CDMA

Sectorization gain can be somewhat of a misleading term. One could think of the  sectorization gain as more of a reduction factor. For an omni site, the sectorization gain is

Power Control Inaccuracy in CDMA

CDMA means all depedancy on power control here i write on Power Control Inaccuracy in cdma. Traffic capacity of CDMA systems is increased by implementing an appropriate power control scheme

Conventional Blocking Analysis for CDMA

Conventional Blocking formula and its Analysis for cdma. In AMPS and TDMA systems, voice/traffic channels are assigned to users as long as they are available. Given the required offered traffic,

Forward Channel Structure in CDMA

Here i write down on how Forward Channel works in CDMA ? and its Structure. The following figure shows an example of the code channels transmitted by a base station.

Reverse Channel Structure in CDMA

The Reverse CDMA Channel is composed of Access Channels and Reverse Traffic Channels. These channels share the same CDMA frequency assignment. Each Traffic Channel is identified by a distinct user
