What is Pseudo-Noise Code and M-Sequence in CDMA

Here I write about Pseudo-Noise Code and what its use Pseudo-Noise Code its two type and Pseudo-Noise Short code is identification for each BTS and Pseudo-Noise Long Code is Identification of each user. Let’s understand basic. A pseudo-noise code (called PN code in short) has properties similar to a noise sequence. It is actually a … Read more

What is Polarization Mode for antenna

The polarization is a radiation feature for indicating the vector special direction of field strength of electromagnetic wave. If unspecified, the spatial direction of electric field vector usually serves as the polarization direction of electromagnetic wave. The spatial direction of electric field vector is the direction of maximum radiation by antenna. The electromagnetic wave of … Read more

CDMA Handoff Defination,Types and Capacity

Handoffs The TIA/EIA Interim Standard, Mobile Station – Base Station Compatibility Standard of Dual- Mode Wideband Spread Spectrum Cellular System (TIA/EIA/IS-95), states that a CDMA base station shall support three types of handoff processes. CDMA to CDMA Hard Handoff A CDMA to CDMA hard handoff is a handoff in which the base station directs the … Read more
