1. INTRODUCCIÓN

El diseño de los sistemas PCM por microondas se hacede acuerdo al diagrama de flujo que se muestra en la fig. 1.

El diseño se divide en las dos partes siguientes:

La selección del sitio, o sea la ubicación de las estaciones; y la evaluación de la calidad del sistema.

Los procedimientos para la selección del sitio es seme_jante a los empleados en otros sistemas, tales como el FDM;en consecuencia, se explica brevemente en este texto.

Para explicar la evaluación de la calidad del sistema,se usan los datos e informaciones del sistema 2S-P2.

En este sistema se emplea la frecuencia de 2 GHz y seconsidera un circuito de referencia de 200 Km. con 8 saltos(7 repetidoras) que puede transmitir 192 canales telefóni -COS.

Sobre la explicación más detallada de sistema PCM pormicroondas, referirse al texto titulado "FUNDAMENTOS DETRANSMISIÓN PCM POR MICROONDAS".

2. SELECCIÓN DEL SITIO

2.1 Diseño de la Ruta de Propagación

(1) Decisión de la altura de la antena

Usando los datos del perfil del trayecto, se pueden de_terminar las alturas de las antenas como sigue:

= A (ho + hs) - _1 (hg2 + ha2) + _L_L hgi (m) .. (1)d2 d2 2Ka

/Xdjt x d2

h0 = / —: (m) (2)di + d9

h0 = Radio de la primera zona de Fresnel

hs = Altura del obstáculo sobre el nivel del mar

-3-

hg , hg2 : Altura de las estaciones sobre el nivel del mar

hai, ha2 : Altura de las antenas sobre el nivel del suelo

En la fig. 2 se muestra el significado de las letras.

(2) Estudio sobre la onda reflejada

(A) Posición del punto de reflexión

Usando el perfil y el mapa, se determina el puntode reflexión y su altura aproximada.

Para el efecto se calcula como sigue:

h i o = tn ~ nr' (3)

En donde, hr es la altura del punto de reflexiónsobre el nivel del mar.

„ hlO ~ n20c =

h10

1 1 d2 (4)m = _ x x

2 2Ka h10 + h2 O

Con los valores de c y m, obtenemos b usando la fi_gura 3.

Con bf se determinan las distancias al punto de re_flexión drl y dr7, como sigue:

dn = - (1 + b)2

dr2 = d - drl . . .. (5)

El significado de las letras se muestra en la fig.

(B) Pérdida de potencia de la onda reflejada

(i) Pérdida en el punto de reflexión (L }

Los valores de las pérdidas dependen de lascondiciones de la superficie terrestre.

La tabla 1 muestra las pérdidas en dB«

(ii) Pérdida por la directividad de la antena (D8)

La pérdida por la directividad de la antenase puede determinar mediante los ángulos entre la onda directa y la onda reflejada (9)7que son calculados a partir de los datos delperfil, de la manera siguiente:

.... (mrad)

(C) Pérdida de potencia de la onda reflejada

(D/ü)r = Lr + DQ1 + D62 (db) ............ (9)

Si este valor es inferior a 10 dB, hay que adop -tar la diversidad f para evitar desvanecimiento det- i no TÍ -

2.3 Diseño de Diversidad

Cuando la pérdida de potencia de la onda reflejada esmenor de 10 dB, se necesita la adopción de diversidad. Enel caso de 2 GHz, usamos el sistema de multi-antena como di_versidad.

La fig. 6 muestra este concepto. La separación de lasdos antenas se calcula como sigue:

Ahd = — (m) (14)28

En donde 9 es ángulo entre la onda directa y la onda -reflejada, en mili-radianes.

2.4 Estudio sobre Interferencias con el sistema de Comuni-caciones por Satélite

Las frecuencias que se usan en el sistema de comunica-ciones por satélite son 4, 5, 6, 11, 15 GHz que se empleantambién en los sistemas terrestres de comunicaciones públ:Lcas.

Por tanto, hay posibilidad de ocurrencia de interiorencias entre ellos. Las relaciones entre los sistemas semuestran en la fig. 7.

2.5 Estudio sobre Interferencias con el Sistema de Radar
